You need this C3 Viewer to be able find that garment files in c3 folder. But if you know the name or the garment or the ID you can just search on the armor.ini to find their Mesh and Texture IDs by changing the last digit number of the garment id to 0 like 184345 to 184340.
1184340 - the first digit 1 is the small female body.
2184340- the first digit 2 is the big female body.
3184340- the first digit 3 is the small male body.
4184340- the first digit 4 is the big male body.
I'm not good at explaining but that conquer editing bible has all the explanation about ID's
