Media File Renamer can add index-number to name of files in a folder
according to order in playlist-file (pls, m3u, txt), track-number in mp3/wma tag, date or filename.
You can choose between renaming the existing files, or making a copy of the files
in a different folder, with the index-number added to the filename.
It can also creates a "playlist"-file with name of all files in a folder,
ordered according to options mentioned above.
Media File Renamer comes in handy, if you are using a media player of some kind,
that cannot read index/track-information from a file, but only according to filename,
as it can add index/track-number to the filenames, so they are played in the correct order
by the media player.
Media File Renamer works on Windows XP, Vista or 7 - it might also work on Windows 2000, but it hasn't been verified.
