Deletable CA files

I plan on adding a cleaner function to my spammer, but I have no clue what files aren't necessary. The .v3d files used to be deletable, I dunno about any more, I know the dump files can be erased, and screen shots, but are there any other files that can be erased without causing runtime errors?

CAV and Endingbanner.

Right on, should've thought of those off top.
