Determining the amount of available hard drive space will vary depending on what operating system you're using. To proceed, select your operating system from the list below and follow the instructions.


Memory (RAM) and hard drive space are two completely different things. If you want to know how much memory your computer has, see our page on how to find how much RAM is installed on a computer.

Windows Vista, 7, 8, and 10 users

  1. Press the Windows key + E to open File Explorer.
  2. In the File Explorer window, on the left navigation pane, click on This PC.
  3. After selecting This PC, you will see a section called Devices and drives.

  1. Each storage device has a status bar, as well as a description of how much memory is free and the total disk space.

If you would like to view additional information, right-click the drive and select Properties from the drop-down menu that appears.

Windows 95, 98, NT 4.x, 2000, ME, and XP users

  1. From the Windows desktop, double-click the My Computer icon.
  2. Within My Computer, highlight and right-click the drive whose capacity you'd like to determine.
  3. In the menu that appears, select Properties.

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, as well as a graph of available space, follow the steps above.


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 16 GB of free space. If you want to see all files and how much space they are occupying, type the following commands.

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 then looking at the status bar at the bottom of the screen.


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