Suppose you want to lock the folder games in d: which has the path
D:\Games.In the same drive create a text file and type

ren games games.{21EC2020-3AEA-1069-A2DD-08002B30309D}
Now save this text file as loc.bat

create another text file and type in it
ren games.{21EC2020-3AEA-1069-A2DD-08002B30309D} games
Now save this text file as key.bat

Now you can see 2 batch files loc and key.Press loc and the folder
games will change to control panel and you cannot view its contents.Press
key and you will get back your original folder.

You can also convert the folder to my computer or recycle bin
Just add the the following codes instead of the code for control panel.
Actually it is known as CLSID(clas ID)

Control Panel:{21EC2020-3AEA-1069-A2DD-08002B30309D}
Recycle Bin :{645FF040-5081-101B-9F08-00AA002F954E}
My Computer :{20D04FE0-3AEA-1069-A2D8-08002B30309D}

Try experimenting with other CLSIDs all of them might work but keep experimenting. and tell if you get something new.
