I have Windows Server 2012 Essentials with a 2TB HDD. The drive is being rapidly filled up lately but I cannot figure out by what. My 2TB HDD has only 99GB of free space remaining. But I cannot find the files that are taking up the space.
When I use Windows Explorer to look at the properties/size of every folder on the root of the HDD, I can only account for less than 200GB of data:
My "Program Files" folders account for about 2GB. My "Program Data" folder is less than 1GB. My "Server Folders" folder is about 140GB. My "Users" folder is about 1GB. And my "Windows" folder is about 25GB. That's all I can find on the drive.
That means I have over 1.5TB of data that I cannot find, and it grows quickly every day.
I ran disk cleanup and it barely found anything to clean. Why can't I find this mystery data, how do I get rid of it? It won't be long until my HDD is completely filled up.
