Hello, I'm trying to recover the pst files that I've lost. I've read many posts and saw that everybody is recommending using GetDataBack. I've purchased this software but I can't find any pst file. It says that I have to write the file extention and file signature in the GDBNT.INI but i don't know how to do this. Please help So, how do i use GetDataBack to recover my pst file? Please please help Thank you very much and have a wonderful day.
