Are the texture files are full wrap designs?

No. The textures, carbon and camouflage files are not full wrap designs. See those files as tools to design your own wrap. You can definitely use many of them without modification but you will still need to panel it for your vehicle wrap. If you have any questions about this process please start by finding a professional wrapping company in your area and go meet with them. They will answer all your questions about vehicle wraps.
