    1) rd <the directory>

    so to delete c:\test\test you'd type rd c:\test\test and you'd be left with c:\test

    2a) format <drive letter>

    to format d, type format d:

    2b) deltree /Y d:\

    this deletes all of d:\

    *NOTE* if you do not have the deltree command, you are not using MS-DOS 5 or higher. On Windows 2000 and XP there's a command prompt, which is not MS-DOS, but a CLI (command line interface). It is more powerful than MS-DOS. Anyway, to do the same in W2000 or XP command prompt, type del d:\*.* /s /f

    3) Several ways to do this, one is to add the CD ROM drive letter to the path environment variable. In proper ms-dos, you'd add the command 'set PATH=%PATH%;<cdrom drive letter>', so if you're cd rom is d:, the 'set PATH=%PATH%;d:\'. This is in the autoexec.bat. On XP you'd go the control panel, system, advanced and there you'll find a button 'enivronment variables'.

    You can then use the batch file you created.

    Or create a batch file that specifies the path

    @echo off

    d:\hi

    or use a parameter

    @echo off

    %1\hi

    For the latter, you'd have to type a d:\

  • 1) type rd directory

    2) format c:\ or del *.*

    3) when you start the .bat file you have to set the directory and the drive letter otherwise it will look for the hi.exe in the hard drive and not the cd

    so it would be d:\hi.exe

    something like

    d:\

    copy *.* c:\{directory}

    haven't had to do DOS in like 10 years but I think that's close to what you'd have to do...
