Glad that I was able to solve this problem.
That Folder lock which you used, uses one of the simplest method of locking a folder. The theory behind it is that, if a folder is renamed, with the extension of a
Command Line Switch (CLSID) of proper entities of windows like, My Computer, My Documents, Control Panel, etc, then instead of opening the original folder, it will open that entity of which CLSID is of.
So, if I rename a folder to
folder.{20D04FE0-3AEA-1069-A2D8-08002B30309D} then that folder will now point to My Computer. Since
20D04FE0-3AEA-1069-A2D8-08002B30309D is the CLSID of
My Computer.
