Computer hard disk drive.

The process to determine the amount of available SSD (solid-state drive) or hard drive space varies depending on what operating system you're using. To proceed, select your operating system from the list below and follow the instructions.


RAM (random-access memory) and hard drive space are two completely different things. For memory, see: How to find how much RAM is installed on a computer.

Windows Vista, 7, 8, 10,and 11 users

  1. Press the Windows key+E to open File Explorer.
  2. In the File Explorer window, in the left navigation pane, click This PC.
  3. After selecting This PC, in the section to the right under Folders, locate the section called Devices and drives.

Drive space in Windows 10

  1. Each storage device has a status bar, the amount of free space available, and the total disk space.

Some versions of Windows 10 don't display the status bar shown in step three. To view a drive's total and available space, hover your mouse over it for a few seconds. A small window appears containing this information.


To view additional information, right-click the drive and select Properties from the drop-down menu.

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

  1. From the Windows desktop, double-click the My Computer icon.
  2. In My Computer, highlight and right-click the drive whose capacity you'd like to determine.

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. To view more information, and 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 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. To see all files and how much space they are occupying, type the following commands.

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.


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

Linux and Unix users
