well, I see you have a ton of sample files/application pages. Folders such as Advertising, chat-user-guid, debug, languages, etc. are they safe to remove? I dump everyone just into one chat channel so I'm just trying to trim. Does it use the Access .mdb that comes with it if it's connected to sql server? What about all the Support*.aspx files?
I guess if you really can't tell me I'll just start removing and see what happens.
