COM files are DOS executable files. The content of a COM file is encoded in binary format and, one of its main characteristics is that its content is limited to 64 Kb of code.

COM extension files are executable files, just like EXE files, except that they do not have metadata or headers or attachments.

This means that the content of a COM file generally consists of directives or natural commands used by built-in DOS resources to perform several operations.

As you may have guessed, these directives and commands are normally carried out through the Windows command line, however, grouping them in a COM file may be convenient for some users and programmers.

The contents of some COM files can be viewed and edited with Microsoft Notepad or any other text editing program.

Some computer virus creators take advantage of the similarity of the COM file extension to the internet domain term name. com, to carry out their attack, either through emails, as attachments, as files posted on the website itself.

• Notepad
• Notepad ++
