Command.com is the DOS command interpreter, which contains all internal DOS commands, such as dir for a directory listing, cd to change directories, type which allows you to read a text file, and so on. External commands are the ones that you'll find .exe or .com files for in the DOS directory, such as format.com, edit.com, fdisk.exe, scandisk.exe and so on.

I don't have a listing handy of all the commands supported by command.com, but take a look at my site below, you'll find a couple of very good DOS instructional sites there. Maybe one will have some more info you can use. A good DOS book might also help, check around in resale shops, used bookstores, libraries etc. and you might find some good ones floating around. The books published by Micro$oft typically aren't the best ones, by the way...

Just found this, I knew I had a list of all the internal DOS commands, but took a while to locate it. Here they are:

DIR Lists the files in the current directory

CD Changes to a different directory

COPY Copies files

RD Removes a directory

DEL Deletes a file

REN Renames a file

DATE Used to display or change the date

TIME Used to display or change the time

VER Displays the version of DOS being used

MD Creates a directory

CLS Clears the screen

All other DOS commands are external commands, which means they require executables to run, as explained above.

Command.com, io.sys and msdos.sys are the system files. io.sys and msdos.sys are hidden. With only these 3 files on the computer, these commands are available. Any other DOS commands not in this list require DOS to be installed or available on a disk. Actually, only command.com must be there for a DOS machine to run, I've made boot disks with only command.com on them, but the sys command copies all three to the disk.

By the way, Directory is the same thing that's called a Folder in Windows...
