How to create a secured and locked folder in Windows XP

Here are the steps to create the protected folder in Windows XP:

• First create a folder that you will use to store your confidential data. For example, I have created a folder called Fonts at the root of my D drive. Since the hidden folder will bring you to the Control Panel, it’s best to name the folder as one of the programs inside there.

• In the same location where you created the new folder, create a new file in Notepad, copy the following below into it, replace Fonts with the name of your folder and save it as loc.bat.

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

• To save the file as a .bat file in Notepad, just put the whole thing in quotes, like “loc.bat” and then click Save.

Now you should have a bat file named loc in the same directory as your Fonts folder, not inside the Fonts folder.

• Create another NotePad file and type in the following listed below and save it as “key.bat”.

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

• Now you’ll have loc.bat and key.bat along with your folder. Go ahead and double-click on loc.bat and your folder will turn into the Control Panel and nothing inside can be viewed. Clicking on it will simply bring you to the Control Panel. You’ll notice the icon should have changed also.

• To view the data inside your folder again, click on key.bat and your folder will return to normal! Pretty simple!

Of course, keeping the key.bat file in the same folder will defeat the purpose of securing the folder, so it’s best to move the key.bat file somewhere else, or even better, put it on a USB stick or CD that only you can access.
Most people will be probably look at the folder and simply ignore it since it has the control panel icon and it links directly there. Of course, if someone knows this trick also, they can create their own key.bat file, etc and open it back up. However, if you’re dealing with someone who can do all of that, it’s best you check out more advanced 3rd party software to lock down a folder.
ALTERNATIVE METHOD:
If you’re having trouble with the above-mentioned method (from what I can see from the comments, a good number of people), then here’s another quick and free way to create a secure folder in Windows XP. There is a very nice program called Free Hide Folder from Cleanersoft that allows you to easily hide your private folders.
Your folders are completely hidden and you must supply a password to open the program to unhide the folders. The personal edition is free, just click the Skip Registration button unless you’re using it for commercial purposes.
