How to Fix “Not Enough Storage” Error on PC

The “Not Enough Storage” error on a PC can be frustrating, especially when you’re trying to install new software, update your system, or save important files. This error typically occurs when your hard drive or SSD runs low on space, but it can also stem from system misconfigurations or temporary files clogging your storage. In this guide, we’ll walk you through practical, step-by-step solutions to resolve the “Not Enough Storage” error and optimize your PC’s performance.

Why Does the “Not Enough Storage” Error Occur?

Before diving into solutions, it’s helpful to understand the common causes of this error:

• Low Disk Space: Your drive is nearly full, leaving insufficient room for new files or updates.
• Temporary Files: Cached files, old system logs, or temporary installation files can consume significant storage.
• Large Applications: Resource-heavy software or games may require more space than available.
• System Misconfigurations: Incorrect settings, such as reserved storage for updates, can trigger the error.
• Fragmented Drive: Fragmented files can reduce available space and slow down your PC.

By addressing these issues, you can free up space and prevent the error from recurring. Let’s explore the solutions.

1. Check Available Storage Space

The first step is to confirm how much free space is available on your PC.

Steps:

1. Open File Explorer (Windows key + E).
2. Click This PC in the left sidebar.
3. Check the storage bar under your primary drive (usually C:).
   • If the bar is red or shows less than 10% free space, you need to free up storage.

Tip: Aim to keep at least 15-20% of your drive free for optimal performance.

2. Delete Unnecessary Files

Clearing out unneeded files is one of the fastest ways to reclaim storage space.

Steps:

1. Open File Explorer and navigate to large folders like Downloads, Documents, or Desktop.
2. Sort files by size to identify large items (right-click > Sort by > Size).
3. Delete unnecessary files, such as old downloads, duplicate photos, or unused videos.
4. Empty the Recycle Bin to permanently remove deleted files.

Pro Tip: Use a tool like CCleaner to automate the removal of junk files, but ensure you download it from a trusted source.

3. Use Disk Cleanup Tool

Windows includes a built-in Disk Cleanup tool to remove temporary files, system logs, and other clutter.

Steps:

1. Type Disk Cleanup in the Windows search bar and select the app.
2. Choose your primary drive (usually C:).
3. Check items like Temporary Files, System Files, and Recycle Bin.
4. Click OK to delete selected files.
5. For deeper cleaning, select Clean up system files and repeat the process.

Note: Be cautious when deleting system files—only remove items you’re sure are unnecessary.

4. Uninstall Unused Applications

Large applications, especially games or editing software, can take up significant space.

Steps:

1. Open Settings (Windows key + I) > Apps > Apps & Features.
2. Sort apps by size to identify the largest ones.
3. Select unused apps and click Uninstall.
4. Restart your PC if prompted.

Tip: If you’re unsure about an app, check its purpose online before uninstalling to avoid removing critical software.

5. Clear Temporary Files Manually

Some temporary files may not be removed by Disk Cleanup. Manually clearing them can free up additional space.

Steps:

1. Press Windows key + R to open the Run dialog.
2. Type %temp% and press Enter.
3. Select all files (Ctrl + A) and delete them.
4. If some files are in use, skip them and delete the rest.

Caution: Only delete files in the %temp% folder, as other system folders may contain critical data.

6. Move Files to External or Cloud Storage

If your drive is still full, consider moving files to an external drive or cloud storage.

Steps:

1. Connect an external hard drive or USB.
2. Copy large files (e.g., videos, photos) to the external drive.
3. Alternatively, upload files to cloud services like Google Drive, OneDrive, or Dropbox.
4. Delete the original files from your PC after confirming the transfer.

Tip: Regularly back up important files to avoid data loss.

7. Disable Hibernation (Optional)

Hibernation mode saves system data to a file (hiberfil.sys), which can take up several gigabytes.

Steps:

1. Open Command Prompt as Administrator (search for cmd, right-click, select Run as administrator).
2. Type powercfg /hibernate off and press Enter.
3. This disables hibernation and deletes the hiberfil.sys file.

Note: Disabling hibernation means you can’t use this power-saving feature, so consider your needs before proceeding.

8. Run Disk Defragmentation

A fragmented drive can reduce available space and cause performance issues.

Steps:

1. Type Defragment and Optimize Drives in the Windows search bar and open the app.
2. Select your primary drive and click Optimize.
3. Wait for the process to complete, then check if the error persists.

Note: Do not defragment SSDs, as it can reduce their lifespan. This is only recommended for HDDs.

9. Adjust Windows Update Storage Settings

Windows reserves space for updates, which can sometimes trigger the error.

Steps:

1. Open Settings > System > Storage.
2. Enable Storage Sense to automatically clean up old update files.
3. Click Configure Storage Sense or run it now and select Delete previous versions of Windows.

Tip: Keep Windows updated to avoid storage-related bugs in older versions.

10. Upgrade Your Storage

If none of the above solutions work, your drive may be too small for your needs. Consider upgrading to a larger HDD or SSD.

Options:

• Internal Upgrade: Install a new SSD or HDD in your PC.
• External Drive: Use an external drive for additional storage.
• Cloud Storage: Subscribe to a cloud service for virtually unlimited space.

Recommendation: SSDs are faster and more reliable than HDDs, making them a great choice for upgrades.

Preventing Future “Not Enough Storage” Errors

To avoid this error in the future:

• Regularly clean up temporary files and unused apps.
• Monitor storage usage with tools like Storage Sense.
• Back up files to external or cloud storage.
• Consider partitioning your drive to separate system files from personal data.

The “Not Enough Storage” error on your PC is manageable with the right steps. By checking your storage, deleting unnecessary files, using built-in tools like Disk Cleanup, and considering upgrades, you can resolve the issue and keep your system running smoothly. Follow the solutions above to reclaim space and prevent future errors.
