A cluttered Windows PC not only takes up storage but can also slow down your system, affecting startup times, app performance, and overall productivity. Freeing up disk space is essential for smooth operation, faster booting, and longer PC lifespan. The good news is that you can reclaim storage using built-in Windows tools and simple techniques, without paying for expensive software.
This guide will show you step-by-step ways to free up disk space in Windows, helping your PC run efficiently in 2026 and beyond.
Why Disk Space Matters
Low disk space can lead to:
-
Slower system performance and longer boot times
-
Frequent freezing or crashes
-
Difficulty installing new programs or updates
-
Reduced virtual memory affecting multitasking
Regularly freeing up storage ensures your computer runs optimally and reduces frustration.
1. Use Disk Cleanup Tool
Windows has a built-in Disk Cleanup tool that quickly removes temporary and unnecessary files.
Steps:
-
Press Windows + S, type Disk Cleanup, and open the app.
-
Select the drive you want to clean (usually C:).
-
Check items like Temporary Files, Recycle Bin, Thumbnails, and Downloaded Program Files.
-
Click OK, then Delete Files.
Tip: For deeper cleanup, click Clean up system files to remove old Windows updates and logs.
2. Remove Temporary Files Manually
Temporary files accumulate over time and take up valuable storage.
Steps:
-
Press Windows + R, type %temp%, and press Enter.
-
Delete all files in the folder (skip any that are in use).
-
Open Settings > System > Storage, and check Temporary Files for additional cleanup.
Manual cleanup ensures extra space and prevents storage bloat.
3. Uninstall Unnecessary Programs
Many PCs have pre-installed apps or software you no longer use.
Steps:
-
Open Settings > Apps > Apps & Features.
-
Review the list of installed programs.
-
Select programs you don’t need and click Uninstall.
Tip: Focus on large programs like old games, trial software, or rarely used productivity apps.
4. Clear Browser Cache
Web browsers store temporary files that can occupy significant space.
Steps:
-
Chrome: Settings > Privacy and Security > Clear Browsing Data > Cached images and files.
-
Edge: Settings > Privacy, Search, and Services > Clear Browsing Data.
-
Firefox: Settings > Privacy & Security > Cookies and Site Data > Clear Data.
Clearing cache not only frees storage but can also improve browser performance.
5. Delete Old Windows Updates
Windows updates create temporary files that remain even after installation.
Steps:
-
Open Settings > System > Storage > Temporary Files.
-
Check Windows Update Cleanup.
-
Click Remove Files to free storage.
Removing old updates is safe if your system is running smoothly.
6. Manage Recycle Bin
Deleted files aren’t permanently removed until you empty the Recycle Bin.
Steps:
-
Right-click the Recycle Bin on your desktop.
-
Select Empty Recycle Bin.
-
Confirm deletion to permanently free disk space.
Tip: Set up automatic emptying in Settings > System > Storage > Storage Sense.
7. Use Storage Sense
Storage Sense is an automated tool that frees disk space regularly.
Steps:
-
Open Settings > System > Storage.
-
Enable Storage Sense.
-
Configure it to automatically delete temporary files, old downloads, or files in Recycle Bin.
This feature keeps your PC clean without manual intervention.
8. Move Files to External Drives or Cloud
Large files like videos, photos, and backups can consume significant space.
Tips:
-
Move rarely used files to an external hard drive or USB drive.
-
Use cloud storage like OneDrive, Google Drive, or Dropbox for documents and photos.
-
Delete local copies after confirming files are safely backed up.
This approach frees internal storage while keeping your files accessible.
9. Reduce System Restore Size
System Restore points take up storage over time.
Steps:
-
Press Windows + S, search Create a restore point, and open it.
-
Select your system drive and click Configure.
-
Reduce the maximum disk space used for restore points.
-
Delete older restore points if necessary.
Reducing space usage for System Restore can free significant storage while keeping recovery options.
10. Compress Files and Folders
Compressing rarely used files reduces storage without deleting them.
Steps:
-
Right-click a folder or file.
-
Select Properties > Advanced.
-
Check Compress contents to save disk space.
-
Click OK to apply.
Compression is ideal for archives, photos, or large documents you don’t access frequently.
11. Disable Hibernation (Optional)
Hibernation stores the system state in a file called hiberfil.sys, which can be several gigabytes in size.
Steps:
-
Press Windows + X, select Windows Terminal (Admin).
-
Type
powercfg -h offand press Enter. -
Hibernation will be disabled, freeing space previously reserved for this file.
Note: Only do this if you don’t use hibernation mode.
12. Remove Duplicate Files
Duplicate files accumulate over time, wasting space.
Tips:
-
Use File Explorer to search for duplicate filenames.
-
Third-party tools like Duplicate Cleaner or CCleaner can safely detect duplicates.
-
Always back up before deletion.
Eliminating duplicates frees both storage and reduces clutter.
