but recovery is NEVER guaranteedIf you know which drive letter it is assigned to, and if you know in which audio format it is, the there are FREE software you can use:
Recuva =
LINKPC Inspector =
LINKRead the documentation on how to use it on both programs "Help" section, as they have completely different user interfaces.
I really hope this helps
Kind Regards
