Type: External (2.0 and later)
Syntax:
TREE [d:][path] [/A][/F]
Purpose: Displays directory paths and (optionally) files in each
subdirectory.
Discussion
When you use the TREE command each directory name is displayed along with
the
names of any subdirectories within it. The display will be in a format
like the
summary below. (Different versions of DOS may display the data in a
slightly
different format.)
First, the root directory and the directories within it are listed
(directory
names listed in a five column display):
DIRECTORY PATH LISTING FOR VOLUME (volume name)
Path is C:
Then each directory within the root is listed:
Path is: C:\(directory name)
Options
/A - Specifies that alternative characters (plus signs, hyphens, and
vertical
bars) be used to draw the tree diagram so that it can be printed by
printers
that don`t support the line-drawing and box-drawing characters (DOS
Versions 4
and 5).
/F - Displays the names of the files found within each directory
listed.
For more information on using the TREE command and other fixed-disk
commands,
refer to Chapter 3, Using Fixed Disks.
