CP/M was the inspiration to MS-DOS. It assigns letters for each drive, however it doesn't use directories. CP/M was a portable operating system, that was popularized because it was cheap, and was not resource intesnsive, unlike Unix which had very restrictive licensing. CP/M was also seen as a popular choice of an OS on the S-100 type machines, although not all machines that ran CP/M had S-100 slots (The Commodore 128 would be a good example of such).
Without doubt the 'killer' application that CP/M had was visicalc. Not to mention there was a port of Zork to the CP/M z80 platform.
