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 My Computer window. If you want to display more information, as well as a graph of available space, follow the above steps.

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 that the 'dir' command be used.

At the MS-DOS prompt, type:

dir <press enter>

At the end of the directory listing, you will 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 16GB of free space. If you want to see all files and how much space they are occupying, type the below commands.

cd\
dir /s

The above command will list all files on your computer (except the hidden files) and give you the total amount of disk space they utilize, as well as the 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 on the status bar at the bottom of the screen, view the available free space and total.

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