Recuva didn't recover a file deleted by Ares (P2P)

hello !

As the title suggests, I inadvertently cancelled a heavy shipment that was about to end with Ares galaxy 2.0.1 (a Peer to Peer Software ! )

(It was cancelled on the field because I had deactivated the request for confirmation before :( )

I tried to find deleted files using "Recuva" for analysis by activating all possible options, and I didn't find the file (winrar file) "___ARESTRA___ ... .rar"

PS: Even if I found files that were prior to my last formatting !! ;)

I know that if the file still exists (which I think is very likely) I must not add file on my hard risk to crush this file, if I hope for recovery! because download directory of ARES is on the same disk that the OS (win xp sp2) and this makes it urgent and delicate!

while you advise me ?
