This is my second post about this problem because it just happened again. This time I tried to erase a folder with a few subfolders on an external USB hard drive. The program hung and would not terminate via the STOP button. I could not kill PDExplorer and had to reboot. When I went back to the folder there was a 62GB! file there. The original folder contained about 60MB. From now on I'm using sdelete. It works fine without ever hanging up. I created a batch file that I can access through the explorer context menu to delete any file or folder.
