All you can try: one of the programs found by googling for XP UNDELETE.
If none of them finds it reliably, it's gone. That's why some people backup the files they don't want to loose in case something happens. Others don't and risk loosing data. Their choice. Your choice also?
I accidently deleted my archived entire outlook pst file from my D: drive, thinking that this is my old PC's email pst file. On a regular basis, I used to transfer my Inbox & Sent emails to my archive folder, which was in D: drive. The deletion bypassed the recycle bin, since it was more than 6.5GB. I could find fragmented system files starting with A011****" and with extensions dll, exe, inf, ver, sys and CAT, when PC Inspector s/w is used, but not my personal folder(2).pst file. Please advise how to retrieve pst file.
