Add a right-click menu item to all files

This method was suggested in an old article from PC Magazine -

You edit file type-specific context menus through Explorer.

·                     Select Options from the View menu

·                     click the File Types tab

·                     select the file type from the list

·                     Click Edit

Now you can edit, add, or remove context menu options. Note that for a few special file types, such as executable files (programs) and batch files, Explorer limits your ability to change the context menu options.

To add a menu choice for all files, start by associating it to a single file type.

·                     Chose Options from the View menu

·                     click on the File Types page

·                     select any file type, and press the Edit button

·                     In the Edit File Type dialog, press the New . . . button and give your new action a distinctive name, say, ZZZNORK

·                     Press the Browse . . . button and locate the application that should perform the action

·                     When you have the command line entered correctly

·                     press OK

·                     press Close

·                     and then press Close again

At this point you may want to right-click on a file of the chosen type and make sure the menu choice is working correctly.

Now run Regedit and search for ZZZNORK:

·                     Press Ctrl-F, enter ZZZNORK, check only the Keys check box, and press Find Next. You should find it under a key with a name formed like HKEY_CLASSES_ROOT\ FileTypeName\shell.

·                     Select Export from the Registry menu and export this branch to TEMP$$$$.REG

·                     Delete the ZZZNORK key and close Regedit

·                     Open TEMP$$$$.REG in your favorite editor and change every occurrence of the file type name to * (a single asterisk)

·                     Change every occurrence of ZZZNORK to the name you want displayed for your new menu item

·                     Save the file

·                     then launch it

You've just added a menu item for all files. To add a menu item specifically for files whose types are not registered with the system, do exactly the same thing, but use the word Unknown in place of the asterisk.
