By the end, you will understand how to manage your disk space and avoid this error in the future.
Quick Note: Prerequisites and Initial Checks
Before starting with the fixes, make sure you check the following:
- Check your current disk space: Open File Explorer, click This PC, and look at your main drive (usually C:). Note how much free space is available.
- Close unnecessary programs: Sometimes apps running in the background use disk space temporarily. Closing them can help.
- Backup important files: Before deleting or moving files, save important documents, photos, or data to an external drive or cloud storage.
Step 1: Use Windows Storage Sense to Automatically Free Up Space
Windows 11 has a built-in tool called Storage Sense that helps clean up junk files automatically. This is the easiest first step.
- Click the Start button and open Settings.
- Go to System > Storage.
- Turn on Storage Sense by toggling the switch.
- Click on Storage Sense to configure it. You can choose how often it runs and what files it cleans, like temporary files and recycle bin contents.
- Click Run Storage Sense now to clean up immediately.
Why this helps: Temporary and unnecessary files can take up a lot of space. Storage Sense safely removes these files without affecting your personal data.
Step 2: Manually Delete Temporary Files
If you want more control, you can manually delete temporary files.
- Open Settings > System > Storage.
- Click on Temporary files.
- Select the types of files to delete, such as Temporary files, Recycle Bin, and Thumbnails.
- Click Remove files to delete them.
Why this helps: Temporary files accumulate over time and can waste gigabytes of space. Deleting them safely frees up room.
Step 3: Uninstall Unnecessary Apps and Programs
Many programs take up significant space and may no longer be needed.
- Open Settings > Apps > Installed apps.
- Scroll through the list and identify apps you rarely use.
- Click the three dots next to an app and select Uninstall.
- Follow the prompts to remove the app.
Why this helps: Removing unused apps frees up valuable disk space and can speed up your PC.
Step 4: Move Large Files to an External Drive or Cloud Storage
Files such as videos, photos, and music can take up a lot of space on your main drive.
- Connect an external hard drive or USB flash drive to your PC.
- Open File Explorer and locate large files or folders, such as those in your Videos or Downloads folder.
- Copy or move these files to the external drive.
- Alternatively, upload important files to cloud services like OneDrive, Google Drive, or Dropbox.
Why this helps: Moving files off your main drive frees space without deleting your data.
Step 5: Use Disk Cleanup Tool for Advanced File Removal
The built-in Disk Cleanup tool can remove system files that are not easy to delete manually.
- Type Disk Cleanup in the Windows search bar and open the app.
- Select your main drive (usually C:) and click OK.
- Click Clean up system files.
- After it scans, check items like Windows Update Cleanup, Temporary Windows Installation Files, and Recycle Bin.
- Click OK and then Delete Files to confirm.
Why this helps: System files from updates and installations can take up space. Disk Cleanup safely removes these to free storage.
Alternative and Advanced Options
- Resize your partitions: If your main partition is too small, use Disk Management to increase its size by shrinking other partitions. This is for advanced users and requires caution.
- Use third-party cleanup tools: Apps like CCleaner can find and remove unnecessary files, but use them carefully and only download from trusted sources.
- Upgrade your storage: If you consistently run out of space, consider adding a larger hard drive or SSD to your PC.
