how to extract an AZP file

[ninjaklan]

I hope someone can help me on this one. I installed the azp plugin for TotalCMD to unpack azp files because I want to edit some of the textures, however I don't have any experience with it, can some one help me out with few answers?

1. I'd liek to know how do you guys edit TGA files? I added TGA format support to my CS5 Photoshop (I use PS for years so it would be easiest way for me to mod there) however when I want to open a file fro mtotalCMD it says 90% that file-format cannot be parsed and it doesnt show any pictures. In 10% cases, it opens a TGA but not the ones I want to edit.

2. Do I need to unpack whole AZP files and edit them then or can I edit them directly from totalCMD without extractin/unpacking them to a specific location?

3. Can someone point me to which AZP files and subfolder contain files/textures of the weapons (such as SCARs) and the new pack of camo uniforms? and aswell as the basic character models (green shirt and woodlandpants)

And lastly, how do I edit DDS files, what are those anyway?

Cheers guys!
