The static "exec()" methods in the java.lang.Runtime class let you run external programs. Be careful, though -- some "DOS commands" are programs, and some are actually build into the CMD.EXE shell program. To run these latter commands (DEL, say, or COPY) you need to use Runtime.exec() to execute CMD.EXE, and get it to execute the commands (not that there's any reason to ever run the DEL or COPY commands, because you can do the equivalent operations in Java just as easily.)
Please don't post the same question to multiple forums here at the ranch. I just deleted another copy of this thread I found in our "Beginner" forum. See here for an explanation.
