Add Commands to Menu

If you using Windows explorer, and you right click on a file, you get a menu with explore, copy, paste, etc. Other programs ie winzip are able to add things to this menu.

How do I go about adding things to that menu.
Secondly can anyone tell me or tell me where to find good documention on how the copy command works?
I want to be able to mimick the copy and paste commands.

Thanks

To mimic copy/paste, just use the FileCopy function.

VB Code:

FileCopy "c:\MyFile.txt", "c:\MyNewFile.txt"

thanks mega, but not what I meant.

I'll figure it out once I figure out how to add something to the context menu.

there some stuff about what programs your fiels opens with in the registry

Code:

---

HKEY_CLASSES_ROOT\aspfile

---
