What’s the “Appdata roaming” folder?

//
I just ran CCleaner and I had at least 100 app data roaming entries, which have never appeared before when running a scan. I’ve been reading articles about app data roaming and I’m a little fuzzy on what it means. My computer’s hooked up to a modem and a router. I do not use wireless for this computer, but I do have it enabled for my iPad touch and the appdata roaming is showing all my activity on this computer. I’m a little concerned about this. I recently did a clean install of Windows due to a virus and I’m about a week in on that clean install and now this has appeared. Also, another interesting problem is that I decided to have a look at the application data folder and I got a Windows pop-up saying, “Access is denied.” Any thoughts?

A couple of things are going on here.

First, AppData\Roaming probably isn’t what you think it is. It doesn’t have anything to do with wireless or the number of people using their computer in different places.
