Explanation:
DIR
Type: Internal (1.0 and later)
Syntax:
DIR [d:][path][filename] [/A:(attributes)] [/O:(order)] [/B][/C][/CH][/L][/S][/P] [/W]
Purpose: Displays directory of files and directories stored on disk.
Discussion
In addition to files and directories, DIR also displays both the volume name and amount of free storage space on the disk (if there are files stored in the current directory). Note that both of these are for the entire DISK, not just for the path you specified.
The DIR command is also useful if you want to know what directories have been created on the specified disk. The directories will be displayed along with the files on the disk. They can be identified by the DIR label that follows the directory name.
Wildcard characters (? and *) can be used to specify groups of files.
For more information on using the DIR command, refer to Chapter 2, Using Common DOS Commands.
When you use the DIR command, it will display all files that match the path and filename specifications, along with their size in bytes and the time and date of their last modification. If you don`t enter one of the options, the entire list will be displayed, even if the list is too long to fit on one screen. To limit the amount of data displayed, use either of the two options described below.
Options
/A:attributes Only the files whose attributes match the ones you specify will be displayed. You can enter a sequence of attributes after the colon. It is not necessary to enter spaces between en
