In addition to checking Windows computer configurations such as RAM and CPU, checking the capacity of the computer’s hard drive is also very important. In this case, users will determine the used capacity of the hard drive and the remaining amount of hard drive to have a reasonable way of storing data.

Purpose of checking computer capacity

Checking laptop hard drive capacity helps users know the used capacity and the amount of free space on the computer or laptop hard drive.

From there, they can plan and arrange data properly. At the same time, they know which applications and software consume the most resources and can choose to remove or delete unnecessary data.

In addition, checking computer capacity and cleaning up bring some benefits such as speeding up the computer, reducing lag, faster computer operations, helping to remove viruses, and malicious software to protect and increase the life of the computer.

How to check computer capacity on Windows 10

Check capacity in My Computer

Nowadays, most computers running Windows 8 and 10 display free capacity directly in the My Computer or This PC interface without any further action needed. Here, you will know the available capacity in the total disk capacity.

Press Windows + E to open File Explorer, here:

For Windows 10, 8/8.1, go to This PC and you will see a list of hard drives on the computer. Displayed is the used capacity of the hard drive and free capacity on each hard drive.
Similar to Windows 10 but with Win 7, choose Computer and Windows XP is My Computer. You will also see the disk capacity of the computer.

Check capacity in Properties

Right-click on the drive you want to check and choose Properties. It will display the used capacity in Used space and the free capacity in Free space. Below is the pie chart displaying the usage.

Check capacity in Disk Management

Disk Management is a utility that allows you to view and manage all internal and external hard drives connected to your computer. In Disk Management, you can format the hard drive, create partitions, and view various information such as status, capacity, and percentage of free capacity. You can also rename the hard drive, assign a specific drive letter, and change the size of partitions on that hard drive.

If you format an external hard drive for the first time, you need to open the Disk Management utility so that the computer can communicate accurately with the external hard drive. Some external hard drives have their own configuration software, but you should check Disk Management to make sure everything is formatted correctly.

To view the disk capacity in Disk Management, press Windows + R to open the Run dialog box, type diskmgmt.msc, and press OK to open the interface.

When the Disk Management window appears, you will see all connected hard drives. The lower half of the screen displays similar information, but instead of the number of volumes, you will see the number and graphical view mode of each connected hard drive and the status of all connected drives.

Note: If Disk Management is the first time, you only need to perform basic functions such as initializing and formatting the hard drive. If you perform advanced functions without knowledge, it may cause problems for the hard drive.

The Disk Management interface will display the total capacity of the hard drives used on the computer. The Disk 0 part displays the total hard disk capacity, and the Capacity part displays the capacity of the disk drives on the computer.

When the hard drive is running out of free capacity, downloaded files will not be stored and the Full Disk error will occur frequently. If you choose drive C as the location for the running operating system or the place to install new software, you should prioritize having a large capacity.

Check free capacity with Command Prompt

Another way to check free capacity is to use Command Prompt. The results are not easy to read because the values are expressed in bytes instead of gigabytes, but you can perform the following command:

wmic logicaldisk get size, freespace, caption.
