Actually the folders All Mail, Drafts, Inbox, Saved, Sent Mail, Spam, Starred, Trash are the standard folders for a gmail account, my guess is you won't be able to get rid of them...    gmail has a different approach at sorting mail than the other accounts... it tags every message with locations....    in this scenario a single message can be in 2 or more folders at the same time...    for example I got a email from ebay, it gets tagged with all mail and inbox if you star it, it'll also have the starred tag, if you archive it, it'll lose the inbox tag.. and so on...    the only tag it can't lose is the all mail unless you trash it...    basically every single mail should be in all mail, they only remain in inbox if you don't archive them...
