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.

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:

Tip: If you are freeing up disk space from the C drive, you can read Disk Cleanup Windows 10 to remove more system files such as the System Restore and Shadow Copies.

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.
