Way 2. Clean Up Disk (Including Large Files and Junk Files)

Many large, useless files and junk files are generated when using applications, software, or Windows systems. You can use EaseUS CleanGenius to scan and delete large files on the system and non-system disks and clean up the disk.

Step 1. Download and run EaseUS Partition Master.

Step 3. After the scanning process, select the useless large files and junk files, and then click Cleanup to clean up the large files.

Way 3. Delete Duplicate and Temp Files

It's inevitable to produce duplicate files. Do not let many copies of the same file eat up your valuable hard drive space. 

To delete the temp files, you can manually delete them by going to: Windows File Explorer > C: > Windows folder > Temp folder and clear files in the folder.

Or you can set up an automatic temporary clean-up plan:

Step 1. Go to Settings > System > Storage.

Step 2. Move to Temporary Files, set up a cleanup plan for 1 day, 14 days, 30 days, or more. 

Way 4. Empty Recycle Bin Regularly

The Windows recycle bin holds deleted files and folders for the long term if you need to recover deleted files someday after deletion. However, the recycle bin folder with too many files would also take up plenty of disk space.

Regularly cleaning up the Recycle Bin will help prevent the drive from filling up and running out of free space. You can manually empty Recycle Bin on your own or set an automatic Recycle Bin clean-up plan with the following steps:

Step 1. Go to Settings > System > Storage.

Step 2. Click "Change how we free up space automatically" and set a plan for "every day," "every week," "every month," etc. 

Way 5. Turn on Cloud Storage Service to Save Files

Cloud is also a good place to save large files, reduce disk usage, and, simultaneously, a good backup location for your valuable data files. Let's see how to free up low-space disk capacity:

Step 1. Sign up for a Cloud drive like OneDrive, Dropbox, or Google Drive.

Step 2. Log in OneDrive, Dropbox, or Google Drive with your account.

Step 3. Select and upload important large files from your PC to the cloud drive.

Step 4. After the uploading, delete the files saved on your local drive.

Way 6. Run Anti-Virus Software to Clean Up Malware Regularly

As we know, sometimes, malware or virus infection may also cause a situation in which the system warns of low disk error, but the disk actually has enough free space.
