Microsoft Windows 2000 and Windows XP users

If you are running Windows 2000 or Windows XP, My Computer also displays the total size and free space for each of the drives in the main window. If you want to view more information, and a graph of available space, follow the steps above.

Tip

You can also view the available space through MS-DOS.

MS-DOS and Windows command line users

Open the MS-DOS prompt.

To determine the available space on a hard drive using MS-DOS, we recommend using the dir command.

At the MS-DOS prompt, type:

dir <press Enter>

At the end of the directory listing, you see information similar to the example below.

2 file(s)                       578 bytes
15 dir (s)               16,754.78 MB free

As you can see above, the hard drive has over 16 GB of free space. If you want to see all files and how much space they are occupying, type the following commands.

cd\
dir /s

The command above lists all files on your computer (except hidden files) and displays the total amount of disk space they utilize, and free disk space.

Windows 3.x and NT 3.x users

In Windows 3.x or Windows NT 3.x, you can determine the available free space by highlighting the C: drive, and then looking at the status bar at the bottom of the screen.
