lock and hide the folder methods in cmd

Method 1 (the sy one)
1. Click �Start�, �Run,� and then type cmd. When the command prompt opens type � 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 � 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! Method 2 (this is where it starts to get slightly more difficult)
