I think it is possible to add our own applications/options to the right click pop up menu(the one that appears when you right click in the client area of a folder window/desktop)..but i dont know what regidtry changes i must make in order to acheive it..
Anyone knows how??

re: Adding Options to Right Click Pop Up Menu

For The folder Right Click it's

HKEY_CLASSES_ROOT\Folder\Shell

For the file Right Click it's

HKEY_CLASSES_ROOT\*\Shell

The Shell key may or may not exist under the * key, if not you will have to create it.

Right Click on the Shell Key and select New Key. Use the name you want to appear in the menu.

Right Click on your new key and select New Key. Name this key command

Doubble click on the default string value for the new command key and enter the command that you want run.
