I have Vista x64 installed on a 75 GB partition. I just noticed it was almost full and started snooping around for the space hog. It turns out it's my AppData\Roaming folder. It's consuming nearly half the partition. I don't know what this folder is, but by the name I'd guess it has something to do with roaming profiles. We don't use roaming profiles.
Can anyone tell me about this folder, why it is consuming so much disc space, and how I can get it back?
