Download a texture via www or assetbundles, and then save it encoded to resources?

Unity Engine

I want to download a texture, either through the www class or through an asset bundle, and then I want to save the encoded texture to the resources folder for quicker access later. How can this be done? I know saving out a PNG is simple. But how do I save out a texture in RGB16 or PVRTC format to the resources folder for later use?

There is no resources folder in a build, that’s something which only exists in the editor. When you make a build, everything in resources is bundled into a file.

Then is it possible to download a file, save it to disk, and then reload it in game any way?
