Are you sure? There is a new protocol for directories... WebAssist changed their hierarchy so that everything now resides in a folder titled "webassist". So, you won't see the exclusive DFP folder unless you look in the webassist folder.
The change was made because so many users (including me too) wanted a much cleaner (better organized) file system. So, WA is now making it so all of the new releases will utilize the "webassist" parent directory.
