How to Lock Or Hide A Folder, A File Or A Drive On The Computer

1. Click “Start”, “Run,” and then type cmd. When the command prompt opens type “CD C:\Test” (replace “Test” with the name of the folder you want to hide.)
2. Now type “attrib file +s +h” and replace “file” with the name of the actual file name you would like to hide.
3. Now, go back to C:\Test and look for your file or folder, it’s not there! You cannot find it through simply browsing around, through the command prompt, or even if you click “Show Hidden Files and Folders”.
4. To find the folder and it’s contents again simply go back to the command prompt, type “CD C:\Test” (of course, again replacing “Test” with the name of the folder,) and then type “attrib filename -s -h”. You should now be able to find your file again!
