Epson 20 - Manual (Page 89)

Whenever you format a hard disk or a diskette, MS-DOS creates one
directory for you. This directory is called the root directory. Any
subsequent directories you create are logically subordinate to the root
directory; that is, they are
subdirectories
of the root directory. A simple
directory structure might look like this:
Root directory
WORDPROC SPRDSHT DOS
This arrangement would enable you to keep your word processing
programs and data files in a directory called WORPROC, your
spreadsheet program and data files in a directory called SPRDSHT,
and the MS-DOS files (as well as the other files copied from your
Reference and Startup diskettes) in a directory called DOS. The few
files that MS-DOS needs to find as soon as you boot your system
(COMMAND.COM, CONFIG.SYS, and perhaps AUTOEXEC.BAT)
could remain at the top level of the structure, in the root directory.
As the number of files in your WORDPROC and SPRDSHT
directories grow, you can create additional directories subordinate to
those two-like this, perhaps:
Root directory
WORDPROC SPRDSHT DOS
This structure would let you segregate your business word processing
files from your personal word processing files and your sales
spreadsheets from spreadsheet files used for financial projections.
Your directory structure may be as simple as this example, or much
more complex. You can organize your disk(s) to suit your own needs,
and you can modify the structure as your needs change.
