I'm prepping to redo my server and was backing up !gnusocial, and noticed I have a 700MB archive of the GS folder. The two largest folders are file (400MB) and .git (275MB). The file folder looks like it contains a bunch of pictures of varying sizes, with the largest being a 13MB gif.

Is there any way to clean up those (and other GS) folders? Would anything horrible happen if I just deleted everything in the file folder?
