COM file extension - Command executable

What is com file? How to open com files?

File extension com is for a long time used for command files. A command file is a text file containing commands to be issued to the operating system.

This was the practice on many of the Digital Equipment Corporation mini and mainframe computer systems going back to the 1970s.

With the introduction of microcomputers this use of files ending with the extension com changed.

In MS-DOS and compatible DOSes, and in 8-bit CP/M, a COM file is a simple type of executable file.

The name of the file format is derived from the file name extension com (not to be confused with the .com top-level internet domain), which was originally the extension used for such files.

However there is no actual association between the file format and the file name extension in any but CP/M and very early versions of MS-DOS.

MIME types:

This com file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.

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 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.
