There are three types of executable programs: com exe and bat.

BAT is different from the first two in that it is a batch file (regardless of Windows or DOS). A bat file is actually a combination of syntax commands or executables. It can be implemented through a texter such as Notepad, where the system invokes commands or other files based on the contents.

Suffice it to say, BAT is actually a text file.

A com exe is a file with an executable structure. Their establishment requires the use of specialized compilation software. (Their structure is much more complex).

It is an installer for Microsoft NT core systems (including WinNT, Win2000, WinXP, etc.), and it is not a batch file type.
