This option enables automatic saving of entered data when the file loses the focus (i.e., when moving to a different file in the File List.
Moving to a different file can either be done with the mouse by selecting another file (or the empty area of the File List), or with the keyboard by moving the arrow keys while the File List has the focus or Ctrl+N (e.g., to keep focus in the Tag Panel).
Mp3tag will keep the modification date of the files, when writing or removing tags.
Mp3tag will read all supported files with the specified file extensions.
You can specify whether Mp3tag should ask, ignore or always save changes made at the extended tags dialog.
Mp3tag can display the first image from the file’s directory as cover art in the Tag Panel if the file has no embedded cover art. You can restrict cover display to embedded cover art with this option.
