Share files are ones which 3rd partys have access to such as when using peer to peer programs like likewire. Kids go beserk downloading music and vidoe when home so check to see if they are using peer to peer and ensure that uploads from your computer are limited as if not 3rd partys can have unfetted access to what ever files you have on your computer. I am on a 12g plan with bigpond and computer is in use minimum 12 hours a day and max i have ever used is 10gig.
