DIR

Displays a list of files and subdirectories that are in the 
directory you specify. A directory is something used 
for storing basic file information, that is, a file list. MS-DOS 
directory structure is discussed in my other documents below:

MS-DOS for beginners --- FORMAT.COM --- FAT & directory 
structure. You can go there to get more information.

Note: The DIR command in Windows 9x/NT/2000 supports wildcard 
"*" before characters. In MS-DOS, if you type "DIR *ONE.TXT", 
this will have the same effect as typing "DIR *.TXT". In those 
versions of Windows, this will have exactly the effect listing 
all TXT files whose first name's last three characters are 
"ONE".

You can set the environment variable "DIRCMD" to let dir command execute 
with a predefined set of switches and parameters each time you call it. 
To do that, set the "DIRCMD" to the set of parameters and switches. For 
example, "SET DIRCMD=/P/W", or "SET DIRCMD=*.TXT".

To get more information, please type "dir /?". If you are using 
Windows 2000 or Windows NT series or MS-DOS, you can type "help 
dir" for detailed help information.
