Opens a directory. All files matching the selected file name filter will be displayed in the file listbox and the chosen file is selected.

Opens a recently opened directory.

Opens a directory. All files matching the selected file name filter will be displayed in the file listbox.

Reload directory. Modified files have to be saved before. Expanded subfolders will be collapsed.

Saves all changed files in the directory. The changed files are marked with a disk symbol in the file listbox. If any file names have been changed, those files will be renamed.

Reverts the changes of one or multiple files. If no files are selected in the file listbox, the changes of all files will be reverted, else only the changes of the selected files are reverted.

The Import dialog can be used to import data directly from a freedb.org server, from a MusicBrainz server, from Discogs, Amazon or other sources of album track lists in textual format.

Import from a freedb.org server is possible using a dialog which appears when From Server: gnudb.org or TrackType.org is selected. The artist and album name to search for can be entered in the two topmost fields, the albums which match the query will be displayed when Find is clicked and the results from www.gnudb.org are received. Importing the track data for an album is done by double-clicking the album in the list. The freedb.org server to import from can be selected as well as the CGI path. The imported data is displayed in the preview table of the import dialog. When satisfied with the displayed tracks, they can be imported by terminating the import dialog with OK.

A search on the Discogs server can be performed using Discogs. As in the gnudb.org dialog, you can enter artist and album and then choose from a list of releases. If Standard Tags is marked, the standard information is imported, e.g. artist, album, and title. If Additional Tags is marked, more information is imported if available, e.g. performers, arrangers, or the publisher. If Cover Art is marked, cover art will be downloaded if available.

A search on Amazon can be performed using Amazon. As in the gnudb.org dialog, you can enter artist and album and then choose from a list of releases. If Additional Tags is marked, more information is imported if available, e.g. performers, arrangers, or the publisher. If Cover Art is marked, cover art will be downloaded if available.

You can search in the same way in the release database of MusicBrainz using From MusicBrainz Release. The workflow is the same as described for From gnudb.org.

Import from a MusicBrainz server is possible using the dialog which appears when From MusicBrainz Fingerprint is selected. The Server can be selected as in the freedb import dialog. Below is a table displaying the imported track data. The right column shows the state of the MusicBrainz query, which starts with "Pending" when the dialog is opened. Then the fingerprint is looked up and if it does not yield a result, another lookup using the tags in the file is tried. Thus it can be helpful for a successful MusicBrainz query to store known information (e.g. artist and album) in the tags before the import. If a result was found, the search ends in the state "Recognized", otherwise nothing was found or multiple ambiguous results and one of them has to be selected by the user. OK and Apply use the imported data, Cancel closes the dialog. The closing can take a while since the whole MusicBrainz machinery has to be shut down.

For the import of textual data, From File/Clipboard opens a subdialog, where several preconfigured import formats are available. The first two, "CSV unquoted" and "CSV quoted" can be used to import data which was exported by the Export dialog. The CSV data can be edited with a spreadsheet, and shall be written using tabs as delimiters. Import should then be possible using "CSV quoted", which is more flexible than "CSV unquoted". However, its fields cannot contain any double quotes. If you only export from Kid3 and import later, "CSV unquoted" can be used as a simple format for this purpose. Note that there are also "Export CSV" and "Import CSV" commands in the context menu of the file list, which use scripts to export and import CSV data in a more complete, powerful and flexible way.

The next format, "freedb HTML text", can be used to copy information from an HTML page of freedb.org. Search an album in freedb and if the desired information is displayed in the web browser, copy the contents to the clipboard. Then click the From Clipboard button and the imported tracks will be displayed in the preview table at the top of the dialog. If you are satisfied with the imported data, terminate the dialog with OK, which will insert the data into the tags of the current directory. The destination (Tag 1, Tag 2 or Tag 1 and Tag 2) can be selected with a combo box. The files in the current directory should be in the correct track order to get their tags assigned. This is the case if they are numbered.

The next preconfigured import format, "freedb HTML source", can be used, if the data is available as an HTML document. Import is possible using the From File button, which opens a file selector, or copying its contents from an editor and then importing from clipboard. This format can be useful for offline import, although the HTML document could also be opened in a browser and then be imported in the first format via the clipboard.

More preconfigured formats, e.g. "Track Title Time", are available. An empty custom format can be created with Add to be set by the user. Two lines below the format name can be set with a regular expression to capture the fields from the import text. The first regular expression will be parsed once per document to gather per-album data such as artist, album, year and genre. The second line is tried to match from the start of the document to the end to get track data, usually number and title. The regular expressions include all the features offered by Qt, which is most of the what Perl offers. Bracketing constructs "(..)" create capture buffers for the fields to import and are preceded by Kid3 specific codes to specify which field to capture. The codes are the same as used for the filename format, besides the codes listed below, any frame name is possible:

For example, a track regular expression (second line) to import from an .m3u playlist could be "%{track}(\d+)\s+%{title}(\S[^\r\n]*)\.mp3[\r\n]". All formats can be changed by editing the regular expressions and the name and then clicking Save Settings. They will be stored in the kid3rc file in the configuration directory. This file can be directly edited to have more import formats or it can be deleted to revert to the default formats. Formats can be deleted using Remove.

Accuracy shows an estimation of how good the imported information matches the given tracks. It uses track durations or file names to calculate the level of similarity in percent. Cover Art shows the URL of the album cover image which will be downloaded.

To check whether the imported tracks match the current set of files, the duration of the imported tracks can be compared with the duration of the files. This option can be enabled with the checkbox Check maximum allowable time difference and the maximum tolerated difference in time can be set in seconds. If a mismatch in a length is detected, the length is displayed with a red background in the preview table.

If the files are ordered differently than the imported tracks, their assigned tracks have to be changed. This task can be facilitated using the Match with buttons Length, Track, and Title, which will reorder the tracks according to the corresponding field. To correct the assignments manually, a track can be dragged with the left mouse button and the Ctrl key hold down, and then dropped at the new location.

When the import dialog is opened, it contains the actual contents of the tags. The tag type (Tag 1, Tag 2, Tag 1 and Tag 2) can be selected using the Destination combo box. The button on the right of this combo box can be used to revert the table to the current contents of the tags. The checkboxes in the first table column can be used to select the tracks which are imported. This can be useful if a folder contains the tracks of both CDs of a double CD and only the tracks of the second CD have to be imported.

To identify the tracks which are imported, it is possible to display the file names or the full paths to the files using the context menu of the table header. The values in the import table can be edited. The revert-button to the right of the Destination combo box can be used to restore the contents of the tags, which can also be useful after changing the Destination.

Almost all dialogs feature a Save Settings button, which can be used to store the dialog specific settings and the window size persistently.

From Tags leads to a subdialog to set tag frames from the contents of other tag frames. This can be used to simply copy information between tags or extract a part from one frame and insert it in another.

As in the import from file/clipboard dialog, there are freely configurable formats to perform different operations. Already preconfigured are formats to copy the Album value to Album Artist, Composer or Conductor, and to extract the Track Number from Title fields which contain a number. There is also a format to extract a Subtitle from a Title field.

The following example explains how to add a custom format, which sets the information from the Subtitle field also in the Comment field. Create a new format using Add and set a new name, e.g. "Subtitle to Comment". Then enter "%{subtitle}" in Source and "%{comment}(.*)" for Extraction and click Save Settings.

The expression in Source can contain format codes for arbitrary tag frames, multiple codes can be used to combine the contents from different frames. For each track, a text is generated from its tags using the Source format, and the regular expression from Extraction is applied to this text to set new values for the tags. Format codes are used before the capturing parentheses to specify the tag frame where the captured text shall be stored. It works in the same way as for the import from file/clipboard.

Import from Tags... is also directly available from the File menu. The difference between these two functions is that the import dialog subdialog operates on all files of the current directory whereas the menu function operates on the selected files (which can be in different directories). The menu function supports an additional code "%{__return}" to return the extracted value, which can be useful with the CLI and QML interfaces.

Import from a freedb.org server using gnudb.org album search. This menu item opens the same import dialog as Import..., but opens directly the gnudb.org dialog.

Import from the TrackType.org server. This menu item opens the same import dialog as Import..., but opens directly the TrackType.org dialog.

Import from the Discogs server. This menu item opens the same import dialog as Import..., but opens directly the From Discogs dialog.

Import from Amazon. This menu item opens the same import dialog as Import..., but opens directly the From Amazon dialog.

Import from the MusicBrainz release database. This menu item opens the same import dialog as Import..., but opens directly the From MusicBrainz Release dialog.

Import from a MusicBrainz server. This menu item opens the same import dialog as Import..., but opens directly the From MusicBrainz Fingerprint dialog.

Like From Tags, but the import is applied to the selected files.

Automatic Import allows one to import information for multiple albums from various web services. If directories are selected in the file list, track data for the selected directories will be imported. If no directory is selected, all directories in the file list will be imported.

The tag type (Tag 1, Tag 2, Tag 1 and Tag 2) can be selected using the Destination combo box.

Profiles determine which servers will be contacted to fetch album information. Some profiles are predefined (All, MusicBrainz, Discogs, Cover Art), custom profiles can be added using the Add button at the right of the Profile combo box.

The table below shows the servers which will be used when importing album information using the selected profile. The import process for an album is finished if all required information has been found, so the order of the rows in the table is important. It can be changed using the Move Up and Move Down buttons. Edit can be used to change an existing entry. The Server selection offers the same servers as can be used in the import functions. Standard Tags, Additional Tags, Cover Art determine the information which shall be fetched from the server. Finally, Accuracy is the minimum accuracy which must be achieved to accept the imported data. If the accuracy is insufficient, the next server in the list will be tried. The same dialog containing the server properties appears when Add is clicked to add a new server entry. Existing entries can be deleted using Remove.

To launch an automatic batch import with the selected profile, click Start. Details about the running import are displayed at the top of the dialog. The process can be aborted with the Abort button.

The Browse Cover Art dialog helps to find album cover art. Artist/Album is filled from the tags if possible. Source offers a variety of websites with album cover art. The URL with artist and album as parameters can be found beneath the name. URL-encoded values for artist and album can be inserted using %u{artist} and %u{album}, other values from the tags are possible too, as described in Configure Kid3, User Actions. More sources can be entered after the entry "Custom Source" by replacing "Custom Source" with the source's name, pressing Enter, then inserting the URL and finally pressing Save Settings. The resulting browser command is displayed at the top of the dialog and can be started by clicking Browse. The browser, which can be configured in the settings, is started with the selected source. A cover image can then be dragged from the browser into the Kid3 window and will be set in the picture frame of the selected files.

Because not all browsers support drag and drop of images and the pictures on websites often have a URL, in such cases Kid3 will receive the URL and not the picture. If the URL points to a picture, it will be downloaded. However, if the URL refers to some other web resource, it has to be translated to the corresponding picture. Such mappings are defined in the table URL extraction. The left column Match contains a regular expression which is compared with the URL. If it matches, the captured expressions in parentheses are inserted into the pattern of the right Picture URL column (at the positions marked with \1 etc.). The replaced regular expression contains the URL of the picture. By this means cover art can be imported from Amazon, Google Images, etc. using drag and drop. It is also possible to define your own mappings.

The Export Dialog is used to store data from the tags in a file or the clipboard. The editor at the top shows a preview of the data to export. If the export data contain tabulator characters, the export is displayed in a table. The data will be generated from the tags in the current directory according to the configured format.

The format settings are similar as in the Import dialog: The topmost field contains the title (e.g. "CSV unquoted"), followed by the header, which will be generated at the begin of the file. The track data follows; it is used for every track. Finally, the trailer can be used to generate some finishing text.

The format fields do not contain regular expressions as in the Import dialog, but only output format expressions with special %-expressions, which will be replaced by values from the tags. The whole thing works like the file name format, and the same codes are used plus some additional codes. Not only the codes listed below but all tag frame names can be used.

A few formats are predefined. "CSV unquoted" separates the fields by tabs. Data in this format can be imported again into Kid3 using the import format with the same name. "CSV quoted" additionally encloses the fields by double quotes, which eases the import into spreadsheet applications. However, the fields shall not contain any double quotes when this format is used. "Extended M3U" and "Extended PLS" generate playlists with extended attributes and absolute path names. "HTML" can be used to generate an HTML page with hyperlinks to the tracks. "Kover XML" creates a file which can be imported by the cover printing program Kover. "Technical Details" provides information about bit rate, sample rate, channels, etc. Finally, "Custom Format" is left empty for definition of a custom format. You can define more formats of your own by adding lines in the file kid3rc in the configuration directory. The other formats can be adapted to your needs.

The source of the tags to generate the export data (Tag 1 or Tag 2) can be selected with a combo box. Pushing To File or To Clipboard stores the data in a file or on the clipboard. OK and Cancel close the dialog, whereas OK accepts the current dialog settings.

Creates a playlist. The format and contents of the playlist can be set by various options.

The name of the playlist can be the Same as folder name or use a Format with values from the tags, e.g. "%{artist} - %{album}" to have the artist and album name in the playlist file name. The format codes are the same as for Export. Create new empty playlist will make an empty playlist with the given name. The extension depends on the playlist format.

The location of the generated playlist is determined by the selection of the Create in combo box.

The Format of the playlist can be M3U, PLS or XSPF.

If Include only the selected files is checked, only the selected files will be included in the playlist. If a directory is selected, all of its files are selected. If this check box is not activated, all audio files are included in the playlist.

Sort by file name selects the usual case where the files are ordered by file name. With Sort by tag field, it is possible to sort by a format string with values from tag fields. For instance, "%{track.3}" can be used to sort by track number (the ".3" is used to get three digits with leading zeros because strings are used for sorting). It is also possible to use multiple fields, e.g. "%{genre}%{year}" to sort using a string composed of genre and year.

The playlist entries will have relative or absolute file paths depending on whether Use relative path for files in playlist or Use full path for files in playlist is set.

When Write only list of files is set, the playlist will only contain the paths to the files. To generate an extended playlist with additional information, a format string can be set using the Write info using control.

Quits the application.

Selects all files.

Deselects all files.

Selects all files of the current directory.

Selects the previous file.

Selects the next file.

Find strings in the file names and the tags. The Find dialog is a subset of the Replace dialog, which is described below.

This function opens a dialog to find and replace strings in the file names and the tags. The set of frames where the search is performed can be restricted by deactivating the Select all checkbox and selecting the frames which shall be searched. There are also search options available to search backwards, case sensitively, and to use regular expressions.

Depending on the number of files, the search might take some time, therefore it can be aborted by closing the dialog.

When Automatically apply format is switched off for the filename format in the configuration dialog, this menu item can be used to apply the configured format to the names of the selected files. This can also be used to check whether the file names conform with the configured format by applying the format to all saved files and then checking if any files were changed (and therefore marked with a disk symbol in the file listbox).

When Automatically apply format is switched off for the tag format in the configuration dialog, this menu item can be used to apply the configured format to the tags of the selected files. This can also be used to check whether the tags conform with the configured format by applying the format to all saved files and then checking if any files were changed (and therefore marked with a disk symbol in the file listbox).

Sets the Text encoding selected in Settings/Configure Kid3.../Tags/Tag 2 for all selected files. If UTF8 is selected, UTF16 will be used for ID3v2.3.0 tags because UTF8 is not supported for this format.

This dialog offers the possibility to automatically rename the currently open directory according to the tags in the files. Several formats are preconfigured to include information about artist, album and year in the directory name. It is also possible to set a custom format and Edit the list of available formats. The following special codes are used to insert tag values into the directory name:

If a directory separator "/" is found in the format, multiple directories are created. If you want to create a new directory instead of renaming the current directory, select Create Folder instead of Rename Folder. The source of the tag information can be chosen between From Tag 1 and Tag 2, From Tag 1 and From Tag 2. A preview for the rename operation performed on the first file can be seen in the From and To sections of the dialog.

Multiple directories can be renamed by selecting them.

If the track numbers in the tags are not set or have the wrong values, this function can number the tracks automatically in ascending order. The start number can be set in the dialog. If only part of the tracks have to be numbered, they must be selected.

When Total number of tracks is checked, the number of tracks will also be set in the tags.

It is possible to number the tracks over multiple directories. The folders have to be expanded and selected.

If Reset counter for each folder is checked, track numbering is restarted with the given number for each directory when multiple folders are selected.

The number tracks dialog can also be used to format existing track numbers without changing the values when the check box left to Start number is deactivated. The total number of tracks will be added if the corresponding check box is active, which can be used to set the total for all selected tracks. If only formatting of the existing numbers is desired, this check box has to be deactivated too.

The filter can be used to display only those files which match certain criteria. This is helpful if you want to organize a large collection and only edit those files which are not in the desired scheme. The expression defining which files to display uses the same format codes which are used in the file name format, import and export.

These codes are replaced with the values for the file, and the resulting strings can be compared with the following operations:

True expressions are replaced by 1, false by 0. True values are represented by 1, true, on and yes, false values by 0, false, off and no. Boolean operations are not, and, or (in this order of precedence) and can be grouped by parentheses.

Some filter rules are predefined and can serve as examples for your own expressions:

If there are any ID3v2.3 tags in the selected files, they will be converted to ID3v2.4 tags. Frames which are not supported by TagLib will be discarded. Only files without unsaved changes will be converted.

If there are any ID3v2.4 tags in the selected files, they will be converted to ID3v2.3 tags. Only files without unsaved changes will be converted.

This opens a simple toolbar to play audio files. It contains buttons for the basic operations (Play/Pause, Stop playback, Previous Track, Next Track, Close), sliders for position and volume and a display of the current position. If multiple files are selected, the selected tracks are played, else all files will be played.

Toggles displaying of the toolbar.

Toggles displaying of the statusbar, which displays longer actions such as opening or saving a directory.

Toggles displaying of the album cover art preview picture.

Empty tags are automatically hidden if this option is active. The File, Tag 1 and Tag 2 sections can be manually collapsed and expanded by clicking on the corresponding -/+ buttons.

Opens the configuration dialog, which consists of pages for tags, files, user actions, and network settings.

Tag specific options can be found on the Tags page, which is itself separated into four tabs for Tag 1, Tag 2, Tag 3, and All Tags.

If Mark truncated fields is checked, truncated ID3v1.1 fields will be marked red. The text fields of ID3v1.1 tags can only have 30 characters, the comment only 28 characters. Also the genre and track numbers are restricted, so that fields can be truncated when imported or transferred from ID3v2. Truncated fields and the file will be marked red, and the mark will be removed after the field has been edited.

With Text encoding for ID3v1 it is possible to set the character set used in ID3v1 tags. This encoding is supposed to be ISO-8859-1, so it is recommended to keep this default value. However, there are tags around with different encoding, so it can be set here and the ID3v1 tags can then be copied to ID3v2 which supports Unicode.

The check box Use track/total number of tracks format controls whether the track number field of ID3v2 tags contains simply the track number or additionally the total number of tracks in the directory.

When Genre as text instead of numeric string is checked, all ID3v2 genres will be stored as a text string even if there is a corresponding code for ID3v1 genres. If this option is not set, genres for which an ID3v1 code exists are stored as the number of the genre code (in parentheses for ID3v2.3). Thus the genre Metal is stored as "Metal" or "(9)" depending on this option. Genres which are not in the list of ID3v1 genres are always stored as a text string. The purpose of this option is improved compatibility with devices which do not correctly interpret genre codes.

When WAV files with lowercase id3 chunk is checked, the RIFF chunk used to store ID3v2 tags in WAV files will be named "id3 " instead of "ID3 ". By default, Kid3 and other applications using TagLib accept both the lowercase and the uppercase variant when reading WAV files, but they use "ID3 " when writing ID3v2 tags to WAV files. As there exist other applications which only accept "id3 " (e.g. JRiver Media Center and foobar2000), this option can be used to create tags which can be read by such applications.

When Mark standard violations is checked, ID3v2 fields which violate the standard will be marked red. Details about the violation are shown in a tooltip:

The ID3 standard documents are available online:

Text encoding defines the default encoding used for ID3v2 frames and can be set to ISO-8859-1, UTF16, or UTF8. UTF8 is not valid for ID3v2.3.0 frames; if it is set, UTF16 will be used instead. For ID3v2.4.0 frames, all three encodings are possible.

Version used for new tags determines whether new ID3v2 tags are created as version 2.3.0 or 2.4.0.

Track number digits is the number of digits in Track Number fields. Leading zeros are used to pad. For instance, with a value of 2 the track number 5 is set as "05".

The combo box Comment field name is only relevant for Ogg/Vorbis and FLAC files and sets the name of the field used for comments. Different applications seem to use different names, "COMMENT" for instance is used by xmms, whereas amaroK uses "DESCRIPTION".

The format of pictures in Ogg/Vorbis files is determined by Picture field name, which can be METADATA_BLOCK_PICTURE or COVERART. The first is the official standard and uses the same format as pictures in FLAC tags. COVERART is an earlier unofficial way to include pictures in Vorbis comments. It can be used for compatibility with legacy players.

If the Mark if larger than check box is activated, files containing embedded album cover art exceeding the given size in bytes are marked red. This can be used to find files containing oversized pictures which are not accepted by some applications and players. The default value is 131072 bytes (128 KB).

Custom Genres can be used to define genres which are not available in the standard genre list, e.g. "Gothic Metal". Such custom genres will appear in the Genre combo box of Tag 2. For ID3v1.1 tags, only the predefined genres can be used.

The list of custom genres can also be used to reduce the number of genres available in the Genre combo box to those typically used. If your collection mostly contains music in the genres Metal, Gothic Metal, Ancient and Hard Rock, you can enter those genres and mark Show only custom genres. The Tag 2 Genre combo box will then only contain those four genres and you will not have to search through the complete genres list for them. In this example, only Metal and Hard Rock will be listed in the tag 1 genres list, because those two custom genres entries are standard genres. If Show only custom genres is not active, the custom genres can be found at the end of the genres list.

Quick Access Frames defines which frame types are always shown in the Tag 2 section. Such frames can then be added without first using the Add button. The order of these quick access frames can be changed by dragging and dropping items.

The combo box Track number field name is only relevant for RIFF INFO and sets the name of the field used for track numbers. Track numbers are not specified in the original RIFF standard, there are applications which use "ITRK", others use "IPRT".

Tag Format contains options for the format of the tags. When Automatically apply format is checked, the format configuration is automatically used while editing text in the line edits. Validation enables validators in the controls with track/total and date/time values. The Case conversion can be set to No changes, All lowercase, All uppercase, First letter uppercase or All first letters uppercase. To use locale-aware conversion between lowercase and uppercase characters, a locale can be selected in the combobox below. The string replacement list can be set to arbitrary string mappings. To add a new mapping, select the From cell of a row and insert the text to replace, then go to the To column and enter the replacement text. When the text to replace starts and ends with a slash ("/"), a regular expression is used. For regular expressions containing capturing groups, occurrences of \1, \2, ... in To are replaced with the string captured by the corresponding capturing group. To remove a mapping set the From cell to an empty value (e.g. by first typing space and then backspace). Inserting and deleting rows is also possible using a context menu which appears when the right mouse button is clicked. Replacement is only active, if the String replacement checkbox is checked.

The table in Rating contains the mapping of star ratings to the effective values stored in the tag. The frames with rating information are listed in the Rating row of the frame list. For these frames, the rating can be set by giving a number of stars out of five stars. Different tag formats and different applications use different values to map the star rating to the value stored in the tag. In order to display the correct number of stars, Kid3 will look up a map in this table. The key to look up the mapping is the frame name, for example "RATING" as used for Vorbis comments or "IRTD" for RIFF INFO. For ID3v2 tags, a combined key is used consisting of the frame ID "POPM" of the Popularimeter frame and its "Email" field, separated by a dot. Therefore, different keys for ID3v2 exist, e.g. "POPM.Windows Media Player 9 Series" for the mapping used by Windows Media Player and Explorer, and simply "POPM" for POPM frames with an empty "Email" field. As multiple entries for "POPM" can exist, their order is important. When Kid3 adds a new Popularimeter frame, it will use the first "POPM" entry to determine the value to be written into the "Email" field. This value will then specify the mapping to be used for star ratings. The first entry is also used if no key was found, it is therefore the default entry.

Besides the Name column containing the keys, the table has columns 1 to 5 for the values to be stored when the corresponding number of stars is given. The other way round, the values determine the number of stars which are displayed for the value stored in the frame. For instance, the row in the table below contains the values 1, 64, 128, 196, 255. The thresholds for the number of stars to be displayed lay between these values and are compatible with what the Windows Explorer uses.

On the page Files the check box Load last-opened files can be marked so that Kid3 will open and select the last selected file when it is started the next time. Preserve file timestamp can be checked to preserve the file modification time stamp. Filename for cover sets the name which is suggested when an embedded image is exported to a file. With Text encoding (Export, Playlist) the encoding used when writing files can be set. The default System can be changed for example if playlists have to be used on a different device.

If Mark changes is active, changed fields are marked with a light gray label background.

The section File List determines which files are displayed in the file list. A Filter can be used to restrict the items in this list to files with supported extensions. To explicitly specify which directories to display in the file list or exclude certain directories, the options Include folders and Exclude folders can be used. They can contain wildcard expressions, for instance */Music/* to include only the Music folder, or */iTunes/* to exclude the iTunes folder from the file list. If multiple such expressions have to be used, they can be separated by spaces or semicolons.

The buttons Filename from tag and Tag from filename in section Format open dialogs to edit the formats which are available in the Format combo boxes (with arrows up and down), which can be found in the File section of the main window.

Filename Format contains options for the format of the filenames. The same options as in Tag Format are available.

The User Actions page contains a table with the commands which are available in the context menu of the file list. For critical operations such as deleting files, it is advisable to mark Confirm to pop up a confirmation dialog before executing the command. Output can be marked to see the output written by console commands (standard output and standard error). Name is the name displayed in the context menu. Command is the command line to be executed. Arguments can be passed using the following codes:

The special code @separator can be set as a command to insert a separator into the user actions context menu. Menu items can be put into a submenu by enclosing them with @beginmenu and @endmenu commands. The name of the submenu is determined by the Name column of the @beginmenu command.

To execute QML scripts, @qml is used as a command name. The path to the QML script is passed as a parameter. The provided scripts can be found in the folder %{qmlpath}/script/ (on Linux typically /usr/share/kid3/qml/script/, on Windows qml/script/ inside the installation directory, and on macOS in the app folder kid3.app/Contents/Resources/qml/script/). Custom scripts can be stored in any directory. If the QML code uses GUI components, @qmlview shall be used instead of @qml. Additional parameters are passed to the QML script where they will be available via the getArguments() function. An overview of some functions and properties which are available in QML can be found in the appendix QML Interface.

The command which will be inserted with %{browser} can be defined in the Web browser line edit above. Commands starting with %{browser} can be used to fetch information about the audio files from the web, for instance

%{browser} http://lyricwiki.org/%u{artist}:%u{title}

will query the lyrics for the current song in LyricWiki. The "u" in %u{artist} and %u{title} is used to URL-encode the artist %{artist} and song %{title} information. It is easy to define your own queries in the same way, e.g. an image search with Google:

%{browser} http://images.google.com/images?q=%u{artist}%20%u{album}

To add album cover art to tag 2, you can search for images with Google or Amazon using the commands described above. The picture can be added to the tag with drag and drop. You can also add an image with Add, then select the Picture frame and import an image file or paste from the clipboard. Picture frames are supported for ID3v2, MP4, FLAC, Ogg and ASF tags.

To add and delete entries in the table, a context menu can be used.

The Network page contains only a field to insert the proxy address and optionally the port, separated by a colon. The proxy will be used when importing from an Internet server when the checkbox is checked.

In the Plugins page, available plugins can be enabled or disabled. The plugins are separated into two sections. The Metadata Plugins & Priority list contains plugins which support audio file formats. The order of the plugins is important because they are tried from top to bottom. Some formats are supported by multiple plugins, so files will be opened with the first plugin supporting them. The TaglibMetadata supports most formats, if it is at the top of the list, it will open most of the files. If you want to use a different plugin for a file format, make sure that it is listed before the TaglibMetadata plugin. Details about the metadata plugin and why you may want to use them instead of TagLib are listed below.

The Available Plugins section lists the remaining plugins. Their order is not important, but they can be enabled or disabled using the check boxes.

Plugins which are disabled will not be loaded. This can be used to optimize resource usage and startup time. The settings on this page take only effect after a restart of Kid3.

Opens a dialog to assign keyboard shortcuts for most of the program functions. There are even functions without corresponding menu or button available, e.g. next file, previous file, select all.
