Rated 5.00 By 1 users
This is THE coolest way to hide and trick folders in Windows. This is best utilized at work or at school where you can carry the key on a USB and just keep the locked folders on the computers you visit often.

The Method



This will be a lock and key method. Where locked the folder will become a Control Panel shortcut. This makes it impossible get in the folder without the key which will revert it back to normal. Ok now to the CODE.(Save as .bat in Notepad)

Lock.bat:
Code:
ren Fonts Fonts.{21EC2020-3AEA-1069-A2DD-08002B30309D}
The folder you lock will need to be named Fonts.

Key.bat:
Code:
ren Fonts.{21EC2020-3AEA-1069-A2DD-08002B30309D} Fonts
For best unlocking temporarily place the .bat file in the same place as the locked folder and click.

Can you explain what that special number (21EC2020-3AEA-1069-A2DD-08002B30309D) is all about.

I'm not completely sure because I got it from a friend and am just posting but, I believe it is the changer acting as the lock and key.

Code:

This is the control panel's default registry key!

And if you want to do this job more securely, follow this method,
Code:
if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-0800 2B30309D}" goto UNLOCK
if NOT EXIST Locker goto MDLOCKER
:CONFIRM
echo Are you sure u want to Lock the folder(Y/N)
set/p "cho=>"
if %cho%==Y goto LOCK
if %cho%==y goto LOCK
if %cho%==n goto END
if %cho%==N goto END
echo Invalid choice.
goto CONFIRM
:LOCK
ren Locker "Control Panel.{21EC2020-3AEA-1069-A2DD-0800 2B30309D}"
attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-0800 2B30309D}"
echo Folder locked
goto End
:UNLOCK
echo Enter password to Unlock folder
set/p "pass=>"
if NOT %pass%==type your password here goto FAIL
attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-0800 2B30309D}"
ren "Control Panel.{21EC2020-3AEA-1069-A2DD-0800 2B30309D}" Locker
echo Folder Unlocked successfully
goto End
:FAIL
echo Invalid password
goto end
:MDLOCKER
md Locker
echo Locker created successfully
goto End
:End
Save this file as Lock.bat
Now create a folder and name that folder as "Locker" remember, other names will now work until u change the code! Now put ur personal documents into the locker folder and then run the Lock.bat file. Give a password then choose y for locking. don't forget the password. The file will disappear in seconds.
If u want to unlock, simply run again the lock.bat and give the password.
Use At Your Own Risk!
Lock.bat and Locker folder must be at same path!

This method has one flaw....Tools>Folder Options>View>Show Hidden Folders
It is now viewable and just click on the folder. No password necessary.
