Curious folder on the root of volume on windows server 2008

Question

We have just set up a new windows 2008 R2 server with three separate raid arrays as drives C:, F: and I:. After installing all the windows updates and Trend Micro anti virus, we see at the root of our F: volume a folder named "c323e2a243c313f307e247fd" containing only an empty folder named "Sandbox". It has unique security applied

Where might it have come from? And what if we delete it?

Answer 1

These folders are often created by Windows when applying updates. I have seen them created both on C: drives and on additional drives. I wouldn't delete it, but then I don't like to delete anything unless I have to. A hard lesson learned.
