Hey guys i have been trying to find some weapon/ armor DDS files from the vanilla game, so i can re-texture them, but i can only find the files from mods i have installed, so does any one know where i can find or download the dds files?

They're in the bsa files, which are compressed archives with the same directory format as the lose files: Data, Data/Meshes, Data/Textures, etc.

You can browse or unzip BSAs with a standalone utility from nexus, or FOMM, IIRC.
