What do you mean by 'overwrote it'? Did you use CCleaner secure deletion or some other software? Did you just copy a same-named file on top of it? Did you edit/save it?
Have you already used Recuva normal scan to look for the file?
Don't use the flash drive for anything at all. Run a Recuva deep scan on the drive and then plough through all the files returned to see what's there. You may find a copy of the file before it was overwritten. If so recover it to your hard drive, don't put anything on the flash drive until you've recovered the file or given up.
I had a file that was current as of 8/22/08. On that day I accidentally saved a version from 3/25/08 and replaced it. I did a deep scan but it shows the file as of 8.25.08 when I opened it and it appears to be unrecoverable. I was wondering if anyone has any ideas. I just downloaded recuva and am not sure I am using it to the best of its ability.
