Lock ur Folder without any software!!!!!!!

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 in same location 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.bat' and 'key.bat' in same loction. Now, Run 'loc.bat' and the folder 'games' will change to control panel and you cannot view its contents.

To retrieve this folder:
Run 'key.bat' and you will get back your original folder.
