Note: I consider this utility obsolete for now (see mod thread). Keeping it here in case I need it in the future or someone finds a use for it.
This utility can quickly add files to your mod outside of ModBuddy. It is specifically useful for adding very many dds files (100s even) in seconds, where ModBuddy gets pretty slow after 10 or so large dds files. It's intended to work in tandem with (not replace) ModBuddy. I use it after every ModBuddy build to add a large number of art assets.
Warning! This is written in PERL, which can be damaging to the eyes. I've included instructions for free download inside the script.
