Hey Everyone, I was going to get a video I rendered from Blender when I found this file called "Previous Systems." I didn't know what it was so I clicked more info and found out that it is 13.79 gigabytes. Right now my hard drive is around 100 gigs, but that's after 2 years of use. I know it will keep filling up, so I want to get rid of un-needed files. So what is this? What will happen if I delete it? Is my computer using it in any way? This was my first iMac, so I didn't use migration assistant or transfer any data. If anyone knows what this file is/does, please tell me!
