I have always noticed when checking Properties of my hard drive a portion of both Free and Used Space is missing but it was never big.
Recently though I saw my Free Space appears to be missing about 50GB.
Used Space is missing about 20.
What causes this?
For clarity I have attached an image...
So I have 1920x1080 and I want to know if it will mess up my monitor over time if I run games in full screen 1280x720 on a 1920x1080 monitor for better frame rate.
