Why is the OS drive always C?

Back in the day Drive A and B where dedicated as floppy drives... so the lowest level for a hard drive had to be C. and the OS drive naturally should be the first drive that appears.

Some things are just that way because someone said it should be that way. no real rime nor reason...

Usually when you had bought a computer way back in the early 90's They usually came with one or two flippy disk. Usually 1 5.25 inch floppy disk and a second 3.5 inch diskette. Or two of the same time. Depending on how it was bought at the time. So usually at that time the A and the B were the floppy drives way back in the good old Disk Operating Systems (Or Dos for short.) The next logical drive for something like a hard drive. the letter C was assigned to it for hard drives themselves. I remember a fad at one point with the 286's up to the 486's where you could use an multi I/O card that could used up to four floppy drives in one system. But you needed some drivers to tell it it had what floppy drives were there. Since most cases. in the bios you only had 2 floppies there.

The OS drive isn't C. The OS drive is "/". :D
