Modding Help Editing vanilla sprites [SOLVED]

I'm trying to retexture certain armors in the game but I can't figure out how to actually open the images in my image editor. Currently the only files I see are .head .legs etc. I may have unpacked the assets incorrectly but I'm not entirely sure. Any help would be appreciated.

 

It appears you have stopped the unpacking process before it finished. The unpacking can take up to 5 minutes and will only tell you when it's done, it won't update you on the progress.

 

Ok I let the unpacking processes finish this time. Thanks for the help.
