Things You Can Do with DOS
The rest of this chapter steps you through procedures
that do some everyday tasks. Read it now to get
familiar with these commands and then
you can use it to
refer to when you really have to do that task.
Just remember, you will have to substitute the names
of your own files for those we have used here-it's that
easy.
Summary of Commands
These are some of the DOS commands. In this section
we discuss the ones marked with an asterisk
(*).
Command Function
CHKDSK Check DiSK makes sure the specified
diskette's files and directory match and
gives
you a status report about the
diskette and memory.
* DISKCOMP DISKette COMPare compares the
contents
of two diskettes and tells you
if they don't match.
* COpy COpy copies the file(s) you specify to
the same or another diskette.

computer.
* DIR DIRectory displays a list of all the files
