MP3 Folderizer

Say you have a whole bunch of MP3 files into a directory and you want to sort them all into directories based on author.

While pretty rudimentary, this script does about all I need.

This PHP script will search for a "-" and consider everything before that in the filename the author. So make sure you name your files in the author-song.mp3 format. It will then proceed to move the file to its respective author named folder. If it does not exist, the script will create it them move it there. If the file already exists in the folder, it will simply move it to a duplicates folder. Handy little script that saved me a lot of time.
