Do you use a program called "File Janitor"?

Has anyone used this software and if so did yours come with instructions? I have just installed this freeware and it appears to be what I was after but I don't want to release it onto all my files without some sort of insight on how to drive it! I found an instructional video on You Tube by the creator but I think it was originally in French (no good to me) and I ended up with no sound at all and the video was so blurry that it told me nothing. If someone knows a link to a manual that would be great but even a couple of basic pointers would give me some level of confidence to let this thing loose.
