Lock your personal folder without using any software.

First, locate the folder which you want to lock. Suppose, DATA is your private folder and it is stored in D:\ drive.

In the same drive ( ie, D:\) you need to create a batch file. For this, Do the following steps:

1. Open Notepad, Start>Programs>Accessories>Notepad
2. Type, ren data data.{21EC2020-3AEA-1069-A2DD-08002B30309D}
3.  Now, take File menu and click Save  (The Save As window appears)
4. Here, Select D drive in the Save in option and give File name as "Lock.bat" (with quotes)
5. Click Save and close it.

Now open D drive where your folder DATA is, there should be a file named Lock, Double click it. Now the folder DATA's icon will be changed to Control Panel icon.
Try to open the folder DATA, it will open the Control Panel instead of your folder. It is Locked!!


To Unlock

To create another batch file.(Do this only when necessary and delete after use.)

1. Open Notepad, Start>Programs>Accessories>Notepad
2. Type, ren data.{21EC2020-3AEA-1069-A2DD-08002B30309D} data
3.  Now, take File menu and click Save  (The Save As window appears)
   
4. Here, Select D drive on the Save in option and give File name as "Unlock.bat" (with quotes)
5. Click Save and close it.

Now, Open D drive and Double click on unlock.bat and you will get back your original folder.
