Models for unity game, in cache or apk?

[RingOfFury]

Copy all those DATA files into 1 folder, have the filenames automatically append, open them with UnityStudio and you should find what you're after.

What do you mean by "let the filenames automatically append?" And do I open them all at once in unity studio, or one at a time? 

Also, by data files, you are referring to the files without extensions in the unitycache folder?

Sorry for the dumb questions, I'm pretty new to this
