Windows Folder Extensions

Intro

Well you all know about file extensions and what they mean etc... But have you heard about a Folder Extension ? I suppose not. Windows has some set of pretty extraordinary extensions for folders, to mark them as something different. Read more to get what I mean...


List of extensions

  • .{9E56BE61-C50F-11CF-9A2C-00A0C90A90CE} Desktop

  • .{645FF040-5081-101B-9F08-00AA002F954E} Recycle Bin

  • .{20D04FE0-3AEA-1069-A2D8-08002B30309D} My Computer

  • .{208D2C60-3AEA-1069-A2D7-08002B30309D} Network

  • .{2227A280-3AEA-1069-A2DE-08002B30309D} Printer

  • .{00022602-0000-0000-C000-000000000046} Video Clip

  • .{00021401-0000-0000-C000-000000000046} Makes it a file



What to do?

Make a New folder and name it something. Now when you rename add one of the following extension to it. (ie Append the .{XXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXX} to the end of the folder name just as adding an extension to a file) and see the changes.

** Try these on a blank folder or a folder that contains nothing important!

Tested on Windows XP, you are welcome to comment about success or failure on other Windows OS's .... This method can be used to hide/protect important folders.. ;)

Try renaming using the DOS prompt.

Run > CMD


Directory of C:\fn

09/04/2007 08:09 PM <DIR> .

can u use the above format for reverting a folder back if it contains more than one word(say,test match).i tried but "wrong syntax" error.(i cud change it to 1 word n then revert)

to use a file in the command prompt, a file that contains more than one word must be typed between quotes. For example: [command] "c:\new folder\my text.txt"
