Adding an Application to the Right Click on Every Folder

Here is how to add any application to the Context Menu when you right click on any Folder. This way you do not have to always go to the Start Menu. When you right click on any folder, you can have access to that application, the same as using Sent To.

1. Open RegEdit

2. Go to HKEY_CLASSES_ROOT\Folder\shell
3. Add a new Key to the "Shell" Key and name it anything you like.

4. Give it a default value that will appear when you right click a folder, i.e. NewKey (use an "&" without the quotes, in front of any character and it will allow you to use the keyboard)
5. Click on the Key HKEY_CLASSES_ROOT\Folder\shell\NewKey
6. Add a New Key named Command
7. Set the (Default) value of the application you want to run.

 For example: c:\program files\internet explorer\iexplore.exe (Include the full path and parameters if you need them)
