This has been a lifesaver. I was clearing out an external hard drive, onto a main hard drive on my windows 7 machine, cut-and-paste. I copied over 122 Gig of data, with a lot of sorting of it into various subfolders, a days work. In the morning, the WHOLE directory wasn't showing, yet a few files were there from a different directory (strange, I know). I Did not delete it, or empty any recycle bin
