For some reason, there is no detailed tutorial on how to do so, and would make things a lot easier if i knew how to do so.

First off, im not wanting to make a single vpk, i know how to do this with out any problem.

I'm wanting to make a multi part vpk file system with a index file (*_dir.vpk).

I have tried the -M option and that still only creates one vpk file.
vpk.exe foldername -M

Am I missing something? Do i need another file for things to be read from?

Any help would be appreciated.
