Big-O Software

i was using a .wav file because thats what it was downloaded as... im going to redownload the file and than make backups and try again... hopefully it wont delete it this time

I tried making an md5 file for a .wav file and it deleted the thing... it made the md5 and said everything was ok but than it turned my 500mb wav file into a 120 byte file and now it wont work anymore... is this program not supposed to work with .wav files or something? should I have converted it to...
