Exactly what files do you need for an upgrade?

Of vBulletin? Because there are a ton of files in the install folder, and while I now know some can be cut out, what about say the ones for vBulletin version 3.0.0 to like 3.5.0 or the like if upgrading from a version of vBulletin 3.7?

I just upload the whole install file, do the upgrade, and then remove the whole install file. I don't think uploading an extra few files during the upgrade is going to matter much.
