Chuck,

You can simply point multiple file extensions to a single handler alias. Look at the entries for .vcx and .vct they both point to Visual.FoxPro.ClassLibrary and that's the only place the Shell extensions need to be placed.

>Yes, But I want it to appear on all the file extensions. I don't want to go though every file extension in the registry and add a new key. What about the ones that are not associated with a program?
