How do I associate all unknown file types with notepad++?

Question

I work alot with billing and files the bank etc. send me files that have date extensions or some counter as an extension:

eg file1.20110315 or file2.123

So the extension changes every time I receive another file.

Is it possible to associate all file types that end in numbers or if not any unknown file types with notepad(++)?

Thanks

Answer 1

You can edit the openas command of the Unknown type, i.e.

HKEY_CLASSES_ROOT\Unknown\shell\openas\command.

Alternatively, you can add a new command if you want to keep the Open As command.

If you want to make Open with Notepad++ the default, edit the default value of the HKEY_CLASSES_ROOT\Unknown\shell subkey.

Answer 2

You can assign the file type "*" in the registry with Notepad++. But I won't reccomend this, since all files, even binary ones, dll's and so on will be associated then.

Answer 3

The article Add "Open with Notepad" to the Context Menu for All Files describes how to do something similar to what you want, and could easily be changed for use notepad++.

I'm not aware of a way to do it for all numeric extensions.
