What Is Taking up Space on My Hard Drive
In the daily usage of computer, you may find hard drive space disappearing and wonder "what is taking up space on my hard drive?" Indeed, it is hard to tell what is taking up disk space simply by looking at installed apps and saved files in Windows Explorer. Luckily, Windows helps you make it out.
Go to Settings -> System -> Storage, you will see all drives listed there. You can select a drive to see what's taking up space.
Besides, you can even click each item to go deeper. For instance, you will be able to see how much disk space an app/game takes.
Right now, we show you how to clean hard drive in multiple solutions.
Fix #1: Delete Unnecessary Files
Here are two approaches for you to do this. The first one is to select and delete some files you no longer use manually. The second one is to make use of Storage Sense. Storage Sense was introduced in Windows 10 version 1703 to get rid of temporary files and stuff in your Recycle Bin. If you have Storage Sense turned on in Settings, Windows can automatically free disk space by removing files you don't need.
If your Storage Sense is still OFF, you can now make it work.
Step 1. Go to Start menu -> Settings -> System -> Storage. Toggle the option for "Storage Sense" ON and click the option "Change how we free up space".
Step 2. In the next window, check what kind of temporary files to delete. You can also press "Clean now" to free up disk space Windows 10 now.
Fix #2: Uninstall Apps You No Longer Need
If you have some programs installed for problem-solving and now they are no longer needed, you can go ahead and uninstall them to free up disk space. To do this, right-click Windows Start menu and click "Programs and Features". Then right click the program you no longer need and choose "Uninstall". Repeat this process to remove the rest unnecessary apps.
Fix #3: Run Disk Cleanup
Disk Cleanup is a built-in tool that deletes temporary and unimportant files. When your hard drive like C drive keeps filling up, you can go ahead and use Disk Cleanup to free disk space. Simple guide is shown below:
Step 1. Go to Explorer and navigate to "This PC". Then right-click the drive you want to clean up and choose "Disk Cleanup" from the best match.
Step 2. After several minutes' calculation, you will be given a new interface listing files in total that can be cleaned as well as the file size taken by each file type. At this time, check the ones you don't want and click OK.
Fix #4: Disable Hibernation Mode
Hibernation in computing is to power down a computer while maintaining its state. If you have enabled Hibernation Mode in Windows, by changing the Folder Options to "Show hidden files, folders and drives" and unchecking "Hide protected operating system files (Recommended)", you will find a file named "hiberfil.sys" located in the C drive, taking several gigabytes' storage space.
To free up disk space taken by this file, you can open CMD and run this command:
Powercfg /hibernate off
By doing this, the "hiberfil.sys" is deleted totally.
Fix #5: Enable Compact OS
Compact OS is introduced with Windows 10. It decreases the operating system's size using the combination of compression and software tricks. It also reduces the footprint of Windows apps to free up disk space, making sense in Windows disk cleanup.
Enabling Compact OS is easy. However, since you are handling the operating system, it is significant to create a system image backup before you proceed.
Step 1. Search for Command Prompt and run it as Administrator.
Step 2. Type the following command to compress Windows 10 and applications and press Enter:
Step 3. This process will take around 20 minutes. When it finishes, you get 2GB around disk space.
Fix #6: Reduce the Size of WinSxS Folder
If your C drive keeps filling up, you can go to C:\Windows to find a folder named "WinSxS". By viewing its properties, you will see it takes quite a lot of disk space (image attached).
The WinSXS folder contains all Windows system components and continues to grow with the time Windows installed. It also builds up unnecessary files like old versions of system components over time.
Now you may ask:
"Can we remove WinSxS folder for Windows disk cleanup?"
Note that you should not delete the entire WinSxS folder or delete some files from it, as this might severely damage your system, making your PC impossible to restart or update. However, you can do the followings to remove the unnecessary files.

Step 2. Set to view by Category and select "System and Security".
Step 3. Select "Schedule tasks" under Administrative Tools.
