How to hide, lock, invincible your files, folders or harddisks

Everyone has certain files that s/he would rather keep private, especially guys. One of the ways to do that is to make such files hidden and bury them deep in the system files. The problem with such approach is that it’s not really convenient if you need to access those files on a regular basis.
So if you’re interested in something more convenient, here are some of the ways to keep “important” files or drives invisible hidden or locked.

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 its 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!Method 2
This works both on Windows XP and Vista, not sure about other Win versions. What this will do is make selected folder invisble, not hidden. The folder will be only visible when you try to highlight it (see below). If you want to make sure that no one discovers it by chance then also move it to the corner of the screen.
Create a new folder.Rename: Highlight the folder and Click ‘F2' button. Hold the ‘Alt’ key and type in 0160 (you won’t see those 0160 numbers while typing them). Press Enter. Note, you have to use the numpad to enter these numbers.Change icon: Righ click the folder >> Properties >> Customize >> Change the icon >> Select the blank one >> Ok.
Method 3 (this is where it starts to get slightly more difficult)This method, unlike the previous one, hides an entire drive instead of individual files or folders:(Before you ever use the registry I HIGHLY RECOMMEND backing up your registry with a tool similar to Registry Tool or CCleaner. You may as well use a manual method similar to this.)1. Go to “Start,” “Run,” and type regedit.2. When the registry editor loads, navigate to: HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersion
PoliciesExplorer3. Right click on “Explorer” and select “New” and “DWORD Value.”4. Name the value NoDrives and select “Decimal” as the base.5. In the value type the number that corresponds with the drive below:(E.g. If you would like to hide drive E, type 16. You may also hide multiple drives by adding the two numbers. E.g. If you would like to hide drives E and G, 16+64=80.)6. Now, after you restart your computer, you should not be able to see the drive.1. Create a folder in a drive for easy access, e.g. C:. (Name it something related to the Control Panel, e.g. Users.)2. Create a new file in Notepad and copy and paste the following into it:ren Users Users.{21EC2020-3AEA-1069-A2DD-08002B30309D}3. Replace “Users” with the name of the folder you created and save the file as loc.bat.(You should now be able to see your folder and the loc.bat file, with the loc.bat in the same directory as the folder Not in it.)4. Now, right-click and create another text file. Copy and Paste the following into it:ren Users.{21EC2020-3AEA-1069-A2DD-08002B30309D} Users
(Make sure to replace the word “Users” with the name of your folder.)6. Now you should see the loc.bat and the key.bat files in the same directory as the folder you created.7. Now, all you need to do is double-click on the loc.bat file and the folder should have an icon that looks like the control panel. If you click on the folder it should redirect you to the Control Panel and thus you have locked the folder.8. Of course, to unlock it, simply double-click on the key.bat file and the folder should turn back into the folder you first created.
