I found the %LOCALAPPDATA% finally just where you said it would be!!! I cliked on show hidden files. It had a date of the task list ersx file of 7:56am this morning. That must have been when the Erase from last night finished. Ok, so it is working and Vista won't allow all of the cluster tips to be erased. But now I understand that the program did do its thing of erasing free space. Joel, did the latest nightly build eliminate the garbage file because I can't find it, nor did I have most of the hard drive fill up from the garbage like it did the first time I used Eraser 6.
