All DOS "Commands" (other than builtin ones which are implemented in command.com) are just executable file names. If something doesn't run, navigate to the directory where it lives with CD or CHDIR (aliases for each other) that change the current directory till you get where you want to go. Use the DIR command to see what's in a directory. Use DIR /P to see one page at a time. Use DIR file.ext to see if a file is in the current directory. Note: DOS maintains a current directory separately for each drive letter. To change drives, type just the letter. For instance, if the current directory is C:\Junk type D: to get to the current directory on D:. That is, changing drives is separate from changing directories within drives. (It's actually a bit worse, but let's leave it at that for now.) Type HELP for a list of commands supported by command.com (the DOS command interpreter). Anything not listed there you run by typing it's file name. If the extension is .exe or .com, you don't need to type it, but it never hurts. More woe: DOS uses so-called 8.3 filenames, that is, names of up to 8 characters (no spaces) with an extension of up to 3 chars. So longer filenames, or those with spaces, get mapped to 8.3 names. An important one is the Program Files directory, which normally gets mapped to PROGRA~1. So if you want to run, say, C:\Program Files\Drive Image\DI.EXE you would navigate something like c:\> cd progra~1 c:\Progr~1> cd drive~1 c:\progr~1\drive~1> di.exe where everything up to > is the prompt from the DOS command interpreter. You enter what's to the right. Use DIR anytime to find out where you are and what's in the current directory. (Don't forget DIR /p if the display rips by so fast you can't read it.) Hint: If you've ever done any unix work, try the unix command to do what you want. Sometimes it works (cd, for example, but forget ls).
