How to Check Total Hard Disk Space in Windows 10?

Understanding your hard disk space is essential for maintaining your computer’s performance and storage management. Many Windows 10 users face issues such as slow system performance, installation errors, or insufficient space for important files. Knowing how to check your total hard disk space can help you organize files, plan upgrades, and ensure your system runs smoothly.

How to Check Total Hard Disk Space in Windows 10?

Checking total hard disk space in Windows 10 is straightforward once you know the steps. 

• Open File Explorer
• Navigate to “This PC”
• Locate your primary drive (usually labeled C:)
• Right-click the drive and select “Properties.”
• Review the total and available space in the “Properties” window

Now, let’s break down each step in detail to make it easy to follow for anyone, even if you are new to Windows 10.

Step 1: Open File Explorer

The first step is to open File Explorer, which is the tool used to navigate files and drives on your computer. To do this, click on the folder icon located on your taskbar. Alternatively, you can press the Windows key and E on your keyboard at the same time. Once File Explorer opens, you will see a navigation pane on the left-hand side. This pane allows you to access your drives, folders, and files easily. For beginners, remember that File Explorer is your main interface for managing your computer’s storage, so familiarizing yourself with it will make checking your hard disk space much simpler.

Step 2: Navigate to “This PC”

After opening File Explorer, look for the “This PC” option in the left-hand navigation pane. Clicking on “This PC” displays all the drives and connected storage devices on your computer. Here, you will find information about your hard disk drives (HDDs) and solid-state drives (SSDs), including external drives if they are connected. This is an essential step because “This PC” acts as a central hub where you can access all storage-related information.

Step 3: Locate Your Primary Drive

In most Windows 10 computers, the primary drive is labeled C:. This is where your operating system is installed and where most programs and files are stored by default. Identifying your primary drive is important because it allows you to see how much space is available for system operations and essential applications. When you see the drive, notice the blue bar beneath it, which provides a visual representation of space usage. A nearly full bar means your drive is running low on storage, which could impact performance.

Step 4: Access Drive Properties

To check detailed storage information, right-click on your primary drive (C:) and select “Properties” from the context menu. This action opens a window that displays both the total disk capacity and the free space available. The Properties window is divided into sections, showing information such as the used space, free space, and the file system type (usually NTFS for Windows 10).

Step 5: Review Total and Available Space

In the Properties window, look for the “Capacity” section. This shows the total hard disk space your drive has. Directly below, you will see “Used space”, which indicates how much storage is currently occupied by files and programs. The “Free space” value tells you how much storage is available for new files and applications. 

For beginners, this is the most crucial step because it provides an at-a-glance understanding of your storage situation. If the free space is low, consider cleaning up files or using an external storage device.

Step 6: Use Settings as an Alternative Method

Windows 10 also allows you to check hard disk space through the Settings app. Click on the Start menu and select Settings, then navigate to System, followed by Storage. Here, Windows 10 provides a summary of all drives and the total space each has. 

This method is particularly useful because it shows storage usage broken down by categories like apps, documents, and temporary files. It is ideal for beginners who want a more detailed breakdown without opening multiple windows.

Important Tips

• Always ensure that your hard disk has at least 15 to 20 percent of free space for smooth performance. 
• Avoid storing all files on your primary drive, as this can slow down system operations.
• Regularly check your disk space using File Explorer or Settings to prevent running into storage issues. 
• Consider using external drives or cloud storage for files you do not need immediately.
• Additionally, using disk cleanup tools built into Windows 10 can help remove temporary files and system caches, freeing up space efficiently. 

FAQs

How do I know if my hard drive is almost full?

If the blue bar in File Explorer under your primary drive is almost filled, your hard drive is nearly full. Also, Windows may display warning messages about low disk space.

Can I check disk space on external drives?

Yes. Connect the external drive and navigate to “This PC” in File Explorer. Right-click the external drive and select “Properties” to view total and available space.

Does freeing up space improve computer performance?

Yes. Having free space allows your operating system to run more efficiently, prevents slowdowns, and ensures programs and updates install without issues.

Is there a difference between HDD and SSD space?

No. Checking the total space works the same for both. However, SSDs are faster than HDDs, which may impact system performance, but not how you check space.
