Thanks for your answer b!z, i have been able also to recover three deleted wallets using recuva where i think my bitcoins might be, its not a lot of money, but i really want to learn how to use and solve these problems, more than the economic loss.

Recuva found three wallet.dat files that renamed to wallet.dat wallet1.dat and wallet2.dat i tried to change names to wallet.dat and making my qt client to read all the wallets and all the times i got the same error message: corrupt file

what command should i use? these wallets btw have different sizes, 72, 88 and 104 KBs.  probably because i received only two payments ?? (its my guess)

what should i try to recover these wallets (which i guess its the same wallet in different moments, its just my guess, i might be wrong)
