COM File Type

- The quick facts

What are COM files and how to open them

Are you having problems opening a COM file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.

What is a COM file?

COM files have multiple uses, and MS-DOS Executable is one of them.

MS-DOS Executable File

Contrary to popular belief, files with the .com extension have no relation to the .com top-level Internet domain names. Files that contain the .com file extension hold executable program files.

These COM files are executable files that contain commands used by MS-DOS - very similar to the .exe files used by the Windows operating system.

How to open COM files

Important: Different programs may use files with the COM file extension for different purposes, so unless you are sure which format your COM file is, you may need to try a few different programs.

We have not yet verified any programs for Windows that work with this specific file format. If you know one, please use the 'Suggest a program' link below. Thanks!
