What happened? Did your drive crash? Did you accidentally delete the data? did you inadvertently overwrite the data?
J&B,
As I understand it, OP lost his song files that were created in BIAB. I can imagine the frustration because I've been there several times.
I think we are only concerned with .mgu and .sgu files and not actual program files.
IIRC,
Recuva will search and examine files ( even for text ) then determine the recoverability. The GUI is straightforward.
