Plutonium

Hi so I'm tryna make my own customs skins I've made the skin got the .iwi file ready but cant find the weapon files for the names can anyone help out please?
Example(what I'm trying to do lol)
I've got my .iwi file with my camo on it and just need to rename said .iwi file to the file name of the sliquifier but for the life of me i cant find out the names( this goes for every weapon) so if anyone could help or just send me a massive text file with every weapons file name i would appreciate it.

AdrX003 holy fuck the world need more people like you bro thank you ive tried for like 2 days and couldnt find the file names anywhere

AdrX003 also mate any chance you know on how to work out which file does what job. For example ive downloaded this pack because i liked the motd PaP camo but it comes with a bunch of other things i dont want aswell but its all just in one zip file and it just says drag and drop them all in. I know that if i just drag and drop the ones i want it will work but i dont know how to identify whats what.
