In .recycled there are a few files "mru$???", which hold path information about (?)recent files (?) but I don't know what to do with them, among them the path of the overwritten file.

I guess my prob is that the file was not deleted, but overwritten (I have no clue how that happend, I wasn't actually working on that file, but wanted to open it with Cubic to read it while I played the program with Hollywood). But the new content of that particular file is 1 byte only, hence I think the old content of that file is probably still there somewhere on the disk. I played with sfsdoctor a bit, but haven't found an option to help me in this case.
