I ran this program against fully corrupted and partially corrupted files in a verity of formats such as bmp, jpg, tif, gif. It failed every time. It fixed nothing, it identified nothing. It also doesn't seem to be able to handle not fixing more than 1 file at a time.
If you like disappointment and wasting time then this is the program for you. It is as useless as congress but not as partisan, and while the program is free I still feel like I was grossly overcharged.
I ran it on a file that I know was corrupt. It came back that there is nothing wrong with the file. However, you can email that file as an attachment to them and they will analyze it and fix it for you. Yeah, right! For a hefty fee I'm sure!
