To lock drives, removable disks and your hard disks, please click here to download Folder Lock. Install Folder Lock in the partition or in the drive you want security in. Or you can also install it in the default program files path.

Then run Folder Lock and set and confirm a new password that is easy for you to remember but hard for someone to guess.

After setting your password, click 'OK' so that you get logged in Folder Lock's control area where you can see a 'browse' link and a 'Lock' button.

Click the 'browse' link given below the 'Lock' button and press 'Lock folders and drives' button. Now select from the list, the drive you would like to lock. This drive will be locked and hidden such that it will be inaccessible, undeletable, unrenamable and secure from viruses and other users of your PC.
