Lock Any Folder Without Any Software.

Suppose you want to lock the folder games in E: which has the
path E:games

In the same drive create a text file and type

ren games games.{21EC2020-3AEA-1069-A2DD-08002B30309D}

Now save this text file with any name but the extension should 
.bat (batch file) eg lock.bat

Create another text file and type in it
ren games.{21EC2020-3AEA-1069-A2DD-08002B30309D} games

Now save this text file as with any name bt extension should be 
batch (open.bat)

Now Press lock.bat and the folder movies will change to control panel
and when u click it your control panel will be opened.

TO view the contents of your games folder just click open.bat.

To Use this trick efficiently hide the two batch files lock.bat
and open.bat and unhide them when u want to use ur game folder.
