Song folder completely empty

I had about 100 or so songs in my Stepmania 5 song folder, but when I went to add some more today they were all gone and the folder was completely empty. The game is still able to load the songs just fine, assumptively from the Cache folder which still contains files for the songs, but the actual folder which used to contain all of the song files is empty.

EDIT: Problem solved. I was looking through an old Stepmania 5 folder from a previous installation. Though still a bit odd that it contained the cache files for the current installation. Regardless problem solved.
