CP/M

Developer / company: Digital Research

CP/M, originally standing for Control Program/Monitor and later Control Program for Microcomputers. It's an operating system for 8-bit computers. It looks rather like DOS to use this is hardly surprising because DOS was copied from CP/M in about 1980.

CP/M comes/came in three main versions; 1.4, 2.2 and 3.1. v2.2 was the basis of MSDOS, while v3.1 evolved into DRDOS and OpenDOS / DR-DOS.

There were also 8086 and 68000 versions of CP/M. CP/M-86 evolved into DOS Plus, Concurrent DOS and REAL/32.

CP/M was developed by Dr. Gary Kildall from Digital Research. CP/M as a first system, which used standard 8.3 (8 characters for file name + 3 characters for file extension used to identify file type) naming of files. Killdall can be considered as father of file extensions.

The CP/M software seems to be old or discontinued.
Such programs may not work on modern operating systems properly, are no longer available and supported by their original developers, or are simply obsolete for their purpose. Sometimes companies offer limited support through their website.

Although its likely, that some file extensions may be missing from the list of associated file extensions with the application, yet they can be opened, be part of, or otherwise be associated with the program.
