2. Delete Unnecessary/Junk Files

Undesired files on your disk can consume significant space, leaving no room for your essential files. Therefore, deleting those unnecessary and junk files is the best and easiest way to free up disk space in Windows 8.

To remove these files, you can use EaseUS Partition Master or the built-in Windows tool - Disk Cleanup using the process below:

Step 1. Run Disk Cleanup and select "Clean up system files."

Step 2. Choose which file types you want to delete and select them to see a brief overview of the file type.

Step 3. Click on the "OK" button, and the file should be deleted

3. Clean Temporary Files via Disk Cleanup

Windows temporary files are momentarily stored files used before being deleted once the task is finished. These files, however, take up a lot of disk space and are not permanently deleted automatically. Therefore, you must manually delete those files to free up disk space in Windows 8.

Here is how you can clean temporary files using Disk Cleanup:

Step 1. Open "Disk Cleanup" and go to "Files to Delete."

Step 2. Select the temporary files, click "OK," and then "Yes" to confirm.

Step 3. Make sure to close the dialog box for system drive properties.

4. Uninstall Unused Software

Uninstalling unnecessary programs can help you free up disk space if your computer has too many programs installed. However, if you remove the program's shortcut from your computer's desktop, it is of no use.

You can follow the steps below to free up disk space in Windows 8:

Step 1. Open "Control Panel" and choose "Programs" and then "Programs and Features."

Step 2. Select the program you want to uninstall and select "Uninstall/Change."

Step 3. Now follow the on-screen directions to uninstall the program.

5. Transfer Large Files to Another Drive

If your computer still indicates insufficient space after you've deleted all the temporary and unnecessary files, some files on your drive may be very large. You can free up disk space by moving those large files to another drive in your computer.

Using the EaseUS Todo PCTrans, you can transfer large installed programs and files from your C drive to another or external hard drive without reinstalling them.

The steps are as follows:

The Todo PCTrans app supports several features, including clearing out junk files, formatting your hard drive, and even assisting you in getting rid of viruses or malware if that is the cause of your disk space being full. You can download EaseUS Todo PCTrans from the official website.

6. Disable Hibernation

Hibernate allows the disk to control power and frequently shields your system from surges in power. Yet, the "Hiberfil. sys" file takes up a lot of space and can slow down your PC. Therefore, it is preferable to disable it on Windows 8 if there is a pressing need to free up disk space.

Use the command line to disable Hibernation by following the instructions below:

Step 1. Click "Start" and type cmd. (Run the command prompt as an administrator.)

Step 2. Type powercfg.exe/hibernate off and press "Enter."

cmd hibernate off

This two-step process disables Hibernation, allowing your drive to work at maximum performance.

7. Defragment Hard Disk on Windows 8

If you don't routinely defrag your hard drive, your computer may run sluggishly and take a long time to boot up. In addition, a too-fragmented hard drive can cause your computer to freeze or have disk space issues.

So, you can use Disk Fragmenter to handle it. Follow the steps below:

Step 1. Search for "Defragment and Optimize Drives" using the search button.

Step 2. Your disk's automatic defragmentation schedule is in the "Optimize Drives" menu. Select your drive to modify the automatic defragmentation cycle and click "Change Settings."

change settings

Step 3. If the hard drive is not configured to defrag automatically, you can manually defragment it by selecting the disk and clicking the "Optimize" button.

This may take some time to complete as defragmentation is a lengthy process.

8. Upgrade to Larger HDD/SSD

You might need to upgrade your HDD or SDD to a larger model if you cannot remove any files from your disk and want to store all your data without sacrificing system performance.

Since moving all the data to a new HDD or SDD is difficult, you may want to use a specialized tool, such as EaseUS Partition Master. In Windows 10/8/7, the EaseUS clone feature enables you to clone an SSD or HDD to a larger one without losing data.

Using the EaseUS Partition Master clone feature helps you move your files to a larger SSD eliminating the need to reinstall Windows and your programs.

Here are the steps you might need to take to clone your HDD or SSD using the EaseUS clone tool:

  • Click the "Clone" from the left menu. Select the "Clone OS Disk" or "Clone Data Disk"  and click "Next".
  • Choose the source disk and click "Next".

Step 2. Select the target disk.

  • Choose the wanted HDD/SSD as your destination and click "Next" to continue.
  • Read Warning message and confirm "Yes" button.

Step 3. View the disk layout and edit the target disk partition size. 

Then click "Continue" when the program warns it will wipe out all data on the target disk. (If you have valuable data on the target disk, back up it in advance.)

You can select "Autofit the disk", "Clone as the source" or "Edit disk layout" to customize your disk layout. (Select the last one if you want to leave more space for C drive.)

Step 4. Click "Start" to start the disk cloning process.

Isn't it amazing how one tool can solve all of your problems? So what are you waiting for? Download it now to increase your Windows 8 disk space and manage your hard drive.


The simplest solution is to remove all unused and junk files and programs from your hard drive, but if that doesn't work, a third-party tool can help you out of this trouble.
