uploading mtl

[DrakeNekron]

I'm currently using the 3d builder program that came with my laptop, which sadly doesnt save anything as dae files. I was told it;s easy to convert obj to dae, but the ones I've uploaded to Blender don't have any texture or color from the original file. Is there a way to upload the mtl files that were created along with the obj's as textures to apply to the dae files i upload? Right now I'm just working with basic texturing and simple shapes, so it shouldnt be that difficult, right?
