What is a com file and how do I open a com file?

COM is a DOS Command File, an executable program capable of being run by MS-DOS and Windows. It is saved in a binary format and is similar to an EXE file, but has a maximum size of roughly 64KB and no header or metadata. It is commonly used for executing a set of instructions while EXE files are used for fully developed programs. The content of a .com file usually consists of directives or commands used by built-in DOS resources to perform certain operations. These commands and directives are normally performed through the Windows Command Prompt. The content of these .com files can be viewed and edited using Microsoft Notepad among other text editing programs.

In the 1970's, on the Digital Equipment operating systems,, .COM was used as a file-name extension for text files containing commands to be issued to the operating system, similar to a batch file.
