Imagine yourself being in the mood for some specific music and finding out that the music collection you keep on your computer is nothing more than a single folder with hundreds of files heaped inside and named something like 'Track01' or 'Adagio'. You may want to consider structuring your music collection, creating separate folders for different types of music, giving descriptive names to files, and adding meta information (so-called tags) to tracks to ease navigation by implementing genres, comments, and even pictures in your music. 'FoxTag Editor' is intended to help you with this task.
This program allows you to import a whole directory of audio files (not only .mp3 files are supported, but also .wma, .ogg, .flac, .ape, and some more), putting them on a general list for you to set some patterns to change the directory structure, rename the files, or tag them. The former two tasks rely strongly on the tag information: files and folders are usually named using the artist/genre/title data stored in audio tracks, which makes the tagging features crucial in such applications. However, it cannot be said that 'FoxTag Editor' fulfils its tagging duty perfectly.
This tag editor does support two major versions of ID3 tags (namely v1.1 and v2), retaining the most used fields of these tags. This allows you, for instance, to fill in such meta information as track artist, title, genre, album, and lyrics, add a comment and attach a picture to an audio file. This data can also be imported from the Internet or guessed from file names according to the patterns you provide. Nevertheless, you will not be able to benefit much from this diversity. For one thing, the tag fields are actually limited to those pre-defined by the developers of this program. You cannot add your own fields and fill them with custom values, despite it is one of the most notable features of ID3v2 tags; thus, you will have to settle for putting the information about composers, performers, recording sites, and many other useful entries into the 'comments' box, just because the program does not offer any appropriate fields for such data. To make matters worse, the program does not allow you to specify any other Internet source of tag information, making you put up with the one it uses by default (which is far from flawless).
Still, if your demands do not go beyond filling in some basic data and tidying up your folder with some .mp3 files, you may give 'FoxTag Editor' a try.
