C:, G: and I: are all harddrives in my computer
H: and J: are part of the G: and I: harddrives, they use fat32 and they're pretty much useless
F: and L: are both usb drives, F using usb 3.0 and L (which is older) is using 2.0
K: is a virtual cd drive that always appears when I plug in L, it's annoying
D: is just a generic dvd drive, E: is a thing that reads off things like sd cards and the sort
I remember a while ago when I had windows 7 my computer claimed I had a floppy drive installed, which I didn't. That was odd.
