Here is what Seyfi84 answered to my question if Wise Folder Hider is a safe program...
wise folder hider is also the same crap. just use 7-zip File Manager and you'll see a 4 dot folder at the root, instead of 3 dot. Both tools are unreliable because they exploit an explorer bug and undefined behaviour of Win32 API.
