TREE [d:] [/F] 
or
TREE [d:][pathname] [/F] [/A]					[new DOS 4.0]

TREE is an external command that lists all directories and sub-directories 
on the default disk drive or the specified disk drive and optionally lists 
the files in them.

d: names an optional disk drive that contains the disk whose directories
    you want to see.

pathname specifies the subdirectory to start the listing, rather than 
    beginning with the root directory.

/F lists the names of the files inside each directory.

/A will NOT use fancy block graphics characters, with indents at each
    subdirectory level. The graphics characters may not work for all code
    pages and printers. [Not supported by OS/2]

TREE will list each pathname, all its subdirectories, and all the files in 
that pathname (if the /F option is present). It can produce this information 
for all the pathnames on the disk. CHKDSK /V can also do this, in a different 
format.
