Hello all, I got a weird problem.

First of all I run 7zip 9.20 on Windows 7 64 bit.

Yesterday I was adding a couple of image files to an already existing zip file that I have been working on, while I was adding the files 7Zip crashed and when I looked in the folder the file was in it was gone! I have already tried to see if I can recover it with a program called MiniTool Power Data Recovery 6.8 but the file can not be found.

Is the file lost forever or are there other places I can look for it?
