And no, it's not one of "those" kind.
My computer the other day complained that C: was getting low on drive space. I don't use C: for much more than OS, a few basic apps and whatever I download to My Docs. Games and large apps go on D: and media goes on E:, so I thought it was a bit odd.
Today I was doing my usual tidy up of the C: drive, moving stuff I downloaded to C: to other drives if I wanted to keep it and I came across a 17GB video file in my videos library under a folder called "Captured". I played it and it was a muted 2 hour video of a recent WoW session I had. Very odd.
I don't have any video capturing software installed, AFAIK WoW doesn't have a built in way to record video and there's no watermarks identifying what software was used to capture it. I have checked the properties as well and can't see anything relating to what captured it either.
Anyone have any clues?
