1. Delete junk files/unnecessary large files

If you find that your hard drive space is being taken up by temporary files or large, unused documents, CleanGenius is an ideal tool. This free and lightweight program can solve many nagging issues, including removing write protection from USB, SD cards, and internal and external drives in Windows 10/8/7.

You can also choose “Clean Up Big Files” to remove unneeded large files, which can help free up a lot of space.

Run Disk Cleanup to remove temporary files.

Disk Cleanup is not the same as defragmenting, which doesn't delete files but rearranges them to make your hard drive more efficient. Disk Cleanup, instead, removes temporary files and other unnecessary data from your hard drive to free up space.

Step 1: Open "This PC", right-click on the system drive, and select "Properties".

Click it, and the program will scan your hard drive and calculate how much space you can free up.

Step 3: When that's done, click "Clean up system files" in the window, and have the tool scan your drive again.

When the scan is finished, click “OK” in the new window that pops up. You'll then see a prompt asking if you're sure you want to permanently delete the files. Click “Delete Files.” Since these only remove unnecessary system files, you don't have to worry about losing anything important.

If Disk Cleanup isn't working in Windows 10, learn how to fix it first.

3. Uninstall bloatware that you don't use

Right-click the Start menu, choose Control Panel, then Programs, and click Uninstall a Program. Select any programs you no longer need, then click Uninstall at the top of the list.

Tip 2: Store your files on an external storage device.

Suggestion 3: Store your files in a cloud drive, such as OneDrive.

Tip #4: Compress large files before backing them up to an image, to save almost half the disk space.

5. Move programs, apps, and games to an external hard drive

If your Windows computer's built-in hard drive is full of installed programs, apps, and games, you can change where these programs are installed. You can free up space on your hard drive by moving programs to an external hard drive, ensuring that the program will run on any other computer. How?

6. Disable Hibernation

When you put your system into hibernation, the contents of your RAM are saved to your hard drive. This allows the state of your system to be preserved without using any power – when you boot back up, you can pick up where you left off. Windows stores the RAM data in the file C:\hiberfil.sys. You can disable hibernation entirely to free up space on your hard drive, which will delete this file.

If you're using it and finding it useful, keep it on. It's entirely up to you.

Step one: Click “Start,” then “Control Panel,” and then “Power Options.” On the left, click “Change when the computer sleeps.”

Step 2: Next, click on “Change plan settings.” In the “Advanced power settings” window, expand the “Sleep” option. Then expand “Hibernate after” and change the minutes to 0 to disable hibernation.

Third, you can Set the number of minutes to wait before sleeping. Click “Apply” and “OK,” and close any remaining windows.

<Step 3>     Review the disk layout and edit the size of the target disk partitions, if necessary.

Here, you can choose to “Adjust disk size automatically,” “Clone as a source disk,” or “Edit disk layout.” (Choose the last option if you want to leave more space for C:.
