Earlier this year I bought a new computer with two hard drives. One a solid state drive and one a regular. I have like 5 big programs on the SSD: Photoshop, Bridge, Creative Cloud, Acrobat, and Windows 10 (plus some smaller ones). I've been getting notifications that my drive is almost full. I looked and have about 25gb of free space available. The SDD is 220 GB. The four adobe programs take up about 6gb total. This means that Windows 10 is eating up roughly 180gb of my SDD. I ran WinDirStat and here are the top files in size for the SSD.
Even looking at this it says my SDD only has about 55GB on it. But when I do a properties check on the C drive it says that I have 198gb used. The adobe photo editing products are on the SSD but the pictures all live on the other drive.
