The .COM extension refers to Command Executable format files. These files were earlier used in the place of the now popular CMD files. The purpose of the COM files is to store COMmand instructions and process them in a batch.
The COM files were among the first file types used on the MS-DOS systems for Command processing. The structure of the file has no header information and is a file that follows a simple format. Combined COM files have the ability to run on multiple platforms and thus are platform independent. In the same directory, a CMD processor would give higher preference of execution to a COM file over an EXE file.
