MS-DOS lets you keep related files together in directories and
subdirectories so they are easier to find and use. See Chapter 3
for instructions on how to use directories.
Epson also includes the XTREE utility with MS-DOS. XTREE
provides simple menus that allow you to move, create, delete,
and rename files and directories. This program is especially
useful on the hard disk drive because of the large number of
files the disk can hold. See Chapter 3 for an introduction to
XTREE or see your MS-DOS Reference Manual for complete
instructions.
The hard disk in your Apex 100\20 has been prepared at the
factory so it contains all the MS-DOS system files and
automatically loads MS-DOS when you turn on or reset the
computer. If your computer does not seem to be working
correctly, however, you may need to repeat some of the
procedures to prepare it for use. If you think this may be the
case, see Appendix F for instructions.
Backing up hard disk files
While the hard disk is very reliable, it is essential to back up
your hard disk files onto diskettes in case you lose some data
accidentally. Make copies of all your system and application
program diskettes before copying the programs to the hard disk.
Be sure to copy your data files to diskettes whenever you revise
them to keep your backup diskettes
up-to-date.
You can use the MENU utility or the BACKUP command to
back up your hard disk files. Use the MENU utility or the
DISKCOPY command to make copies of your system and
application program diskettes. For instructions on using these
programs, see Chapter 3 (or see your MS-DOS manual).
