My laptop started to have a random Local Disk D (it wasn't there before, I just found it today). I'm not sure where it came from. The disk is 43.2 MB free of 462 MB. When I click on it, I don't see anything in there. I'm not sure why it is full nor what that is as it just appeared today. It may have slowed down my laptop's performance but I'm not sure yet. Is there a way to empty it or what is it?
I just bought a Dell XPS 13 9380, 16GB RAM, 512 GB SSD a few days ago.
