You can use switches with BACKUP to back up files created after a certain date or to specify files stored in a certain directory. You can also tell BACKUP to add only those files that have been modified since the last time you ran BACKUP. This process speeds up backup procedures you perform on a regular basis.

For complete instructions on the use of BACKUP and RESTORE, see your MS-DOS manual.

Note

An easy way to perform the functions of the BACKUP, RESTORE, COPY, and DISKCOPY commands is through the MENU program. See the section on MENU later in this chapter. You can also use the MS-DOS XCOPY command to copy one or more files; see your MS-DOS manual for derails.

Deleting Data

To delete a file, type DEL and then the full name (including the extension, if any) of the file you wish to delete. For example, to delete the file named APRIL.TXT from the current directory; you would type the following and press Enter:

DEL APRIL.TXT

You may delete all the files in the current directory at once by typing the following and pressing Enter:

DEL *.*

For your protection, when you type DEL *.* MS-DOS asks if you are sure that is what you want to do. If you are sure, press Y, then Enter.

You can also use the ERASE command to delete files. ERASE works exactly like the DEL command.
