Lock a Folder in XP!!!

If you want to make your folder private, then you will use a software, but in Windows XP, there is a trick to lock a folder without a software!!!. Just follow the given steps below,

1. Create a folder and name it whatever you want. Assume that your folder name is "private".

2. Create a notepad file by Right clicking your mouse > New > New Text Document. Then in the notepad file type the following statement correctly ren private private.{21EC2020-3AEA-1069-A2DD-08002B30309D} and save the file as lock.bat in the drive where you created your folder named private

3. Create a another notepad file by following the above steps, then in the notepad file type the following statement correctly ren windows.{21EC2020-3AEA-1069-A2DD-08002B30309D} private and save the file as unlock.bat in the drive where you created your folder named private

4. That's it! If you clicked on the lock file, then your folder will link to control panel and your folder contents cannot be viewed, and if you click unlock then it can be viewed normally.

This trick will not work in Windows Vista!
