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 actually hold executable command files.
These COM files are executable files that contain commands that are used by a computer's operating system, very similar to the .exe files used by the DOS and Windows operating systems.
The .com file extension may also be used for Common Object Module files. The EICAR anti-virus software application also uses files with the .com file extension. In this case, the COM files contain anti-virus test files that are used by the software.
Unfortunately we have not received enough suggestions for software that can open COM files yet.
File.org aims to be the go-to resource for file type- and related software information. We spend countless hours researching various file formats and software that can open, convert, create or otherwise work with those files.
If you have additional information about the COM file format or software that uses files with the COM suffix, please do get in touch - we would love hearing from you.
