My HDD/SDD is running dangerously low on space and I don't know where it's going. I did only have around 6-9Gb or so left a few days ago, and now it's down to 300Mb. Was 500-900Mb just the other day. It's boggling my mind where it's vanishing to. I've done a disk cleanup, but there's hardly anything there. I've run checkdisk, which it found and fixed some issues the other day, but nothing related to this. The more intense software I use - Maya, 3ds Max, ZBrush, and Photoshop - have had their scratchdisks moved to another HDD, so they can't be eating up space. Actually, I'm not sure Max and Maya even use them. Is there any way I can find out where space has vanished to lately? Or some other things I could check?
