ATC, ATT, DISATC and UPG custom path?

[Æasir]

Hello, i am fairly new in the modding scene for Warcraft 3 and i was tinkering around with some PNGs and JPEGs for my icons via the Button Manager program, and i have a question: What are those above mentioned files in the title and how to i create a custom path for them so they can work properly in game and not have green boxes whenever i pause?

As far as I know, they don't matter. All you need is two different icons with two paths: ReplaceableTextures\CommandButtons\IconName.tga and ReplaceableTextures\CommandButtonsDisabled\IconName.tga.
