I just recently had to reformat my drive because of some problems I was having. When I reformatted, I partitioned the drive into 2 sections (Macintosh HD for normal use, and Backup for emergencies). When I finished setting up, I noticed that my root folder had more folders than usual. Is this normal? Are they screwed up? Can I move them? Why are they there? Sorry for so many questions, but I find this a bit odd. Attached is the root folder of Macintosh HD
