Tell your friend to go into the DTC - chose her account - ftp accounts, click her ftp account name, and edit it and set the path to the last option.
/accountname.furtopia.org/subdomains/www/html/
she probably chose / or one of the others which is showing her root account folders, while it'll make saving her email logs easy, if she accidently deletes something she could mess up her web account, so if she's fairly newbie-ish, she should probably go with the above ftp filestructure.
