Lock A Folder Without Installing Any Software

A very useful trick to lock a FOLDER. This trick has only been tested in Windows XP.

Suppose you want to lock the folder lucky in d: which has the path D:\lucky. In the same drive create a text file and type
ren lucky lucky.{21EC2020-3AEA-1069-A2DD-08002B30309D}
Now save this text file as lock.bat

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

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