Running out of storage on Windows can slow your PC to a crawl, cause apps to crash, and even block important updates from installing. The good news? You don’t need special software or technical skills to reclaim gigabytes of space in just a few minutes.
In this step-by-step guide, you’ll learn the fastest and most effective ways to clear junk files, remove hidden bloat, and optimize storage with tools already built into Windows. Whether your drive is almost full or you just want to boost performance, these quick methods will free up space instantly and keep your PC running smoothly.
Delete temporary files using Windows storage settings
Windows includes powerful built-in tools that can clear several gigabytes of junk in seconds. Using the Storage settings menu is one of the fastest ways to remove clutter without installing anything extra.
Use Storage Sense to remove junk instantly
Storage Sense automatically wipes temporary files, cached data, and other unnecessary items.
- Cleans out system-generated junk with one click
- Frees up space every time it runs
- Can be scheduled to run automatically
Clear temporary system and app files
Many apps leave behind temp files long after you stop using them.
- Deletes cache files from Windows and installed apps
- Removes leftover data from installers and updates
- Helps improve performance for apps that rebuilt cache efficiently
Remove old Windows Update leftovers
Windows keeps large update backups “just in case,” but they take huge space.
- Clears outdated update files safely
- Reclaims several gigabytes on systems that haven’t been cleaned recently
- No effect on current updates or system stability
Uninstall unused apps and bloatware
Unused apps, games, and preinstalled software can quietly consume several gigabytes of storage. Cleaning them out not only frees space instantly but can also improve performance. Windows makes it easy to identify large apps and remove anything you no longer need.
Identify large apps taking up unnecessary space
Before uninstalling, check which apps are consuming the most storage.
How to check app sizes:
- Open Settings
- Go to Apps
- Select Installed apps
- Click Sort by → Size
This instantly shows the biggest storage hogs at the top.
- Large games, editing tools, and old programs often take several GB
- Trialware and leftover software from old devices are common culprits
- Uninstall anything you no longer use to reclaim space quickly
Remove preinstalled apps you don’t use
Windows laptops often ship with manufacturer bloatware and unnecessary apps.
How to remove them:
- Open Settings → Apps → Installed apps
- Select the app you want to remove
- Click Uninstall
You can safely delete:
- Manufacturer tool suites you never open
- Trial antivirus programs
- Retail demo apps
- Duplicate media players or note apps
This provides an instant storage boost without affecting system stability.
Use third-party tools for deeper app cleanup (optional)
Some apps leave behind leftover files, registry entries, and caches even after uninstalling. Third-party tools can remove these traces automatically.
Recommended tools:
- Revo Uninstaller – cleans leftover files after standard uninstalls
- Geek Uninstaller – lightweight and portable
- HiBit Uninstaller – good for removing stubborn or broken apps
Advantages over Windows’ built-in uninstall:
- Removes hidden leftover folders
- Cleans registry entries
- Helps uninstall apps that Windows refuses to remove
(Optional tools are helpful but not required—Windows’ built-in uninstaller is safe and sufficient for most users.)
Clean up large files you don’t need
Large videos, old installers, and forgotten downloads can quietly take up gigabytes of space. Cleaning these out is one of the quickest ways to free storage instantly—especially on SSDs where space is valuable.
Sort files by size in File Explorer
Windows makes it easy to locate oversized files hiding in your folders.
How to find large files:
- Open File Explorer
- Select a drive (usually Local Disk C:)
- In the search bar, type: size:>1GB (or try size:>500MB)
- Press Enter
- Sort results by Size
You’ll immediately see the biggest files on your system.
- Finds hidden space hogs you forgot about
- Great for locating huge videos, ISOs, and old backup files
- Works on any folder or drive
Delete or move large videos, installers, and archives
Once you identify large files, you can choose what to delete or offload.
Common large files to remove or move:
- Old screen recordings or downloaded movies
- Game installers and setup files (safe to delete after installation)
- ZIP/RAR archives you don’t need anymore
- ISO images or firmware installers
If you want to keep them, move them to:
- An external hard drive
- A USB stick
- Cloud storage (OneDrive, Google Drive, etc.)
This immediately frees up internal SSD space without losing anything important.
Use built-in “Storage recommendations” for quick cleanup
Windows 11 offers a smart tool that scans your system and recommends files to delete.
How to access it:
- Open Settings
- Go to System
- Select Storage
- Click Storage recommendations
Here, Windows shows categories like:
- Large or unused files
- Unused apps
- Files in Downloads you rarely touch
- Temporary files
You can select everything you want to delete and remove it with a single click—no manual searching required.
Empty the recycle bin
The Recycle Bin often holds gigabytes of files you thought were already deleted. Clearing it is one of the quickest ways to free space instantly—especially if you regularly delete large videos, photos, or documents.
Check how much space is stuck there
Before emptying the bin, you can easily see how much space it’s taking.
How to check Recycle Bin size:
- Right-click the Recycle Bin icon on your desktop
- Select Properties
- View the size or maximum storage limit
You can also simply open the Recycle Bin and look at the total size at the bottom.
- Many users find 5GB–20GB stuck in the bin
- Files stay there indefinitely unless manually removed
- Clearing it instantly frees that space on your drive
Set Windows to auto-empty the bin
If you don’t want to worry about clearing it manually, Windows can do it automatically.
How to set auto-empty:
- Open Settings
- Go to System → Storage
- Enable Storage Sense
- Click Configure Storage Sense
- Under Temporary files, set:
- “Delete files in my recycle bin if they’ve been there for” → choose 1 day, 14 days, or 30 days
- “Delete files in my recycle bin if they’ve been there for” → choose 1 day, 14 days, or 30 days
Benefits of auto-empty:
- Prevents the bin from filling up your SSD
- Never forget to clear old deleted files
- Hands-off storage maintenance
Permanently delete old items safely
If you want immediate space gain:
To empty manually:
- Right-click Recycle Bin
- Choose Empty Recycle Bin
- Confirm deletion
To delete specific files only:
- Open Recycle Bin
- Select the files you want to remove
- Press Delete
This removes the items permanently, freeing space instantly while letting you keep anything you still want to review.
Clear browser cache and downloads
Browsers store cached images, cookies, and temporary data to speed up websites—but over time, these files can pile up and take several gigabytes of space. Cleaning them, along with your Downloads folder, is one of the fastest ways to reclaim storage instantly.
Remove cached files from Chrome, Edge, Firefox
Each browser has a built-in tool for clearing temporary data.
Google Chrome
- Open Chrome
- Press Ctrl + Shift + Delete

- Enable Clear browsing data on exit
- Select cache, cookies, and history
Windows Storage Sense can also clear Downloads:
- Go to Settings → System → Storage
- Turn on Storage Sense
- Set Delete files in my Downloads folder if they haven’t been opened for → choose Never, 30 days, etc.
Use Disk Cleanup for deep system removal
Disk Cleanup is one of Windows’ most powerful built-in tools for removing files that normal storage settings can’t touch. It digs into system-level junk—like logs, error dumps, and outdated installation files—that often accumulate quietly in the background. Using it can instantly free up several gigabytes.
Remove old system logs and temporary files
System logs and temporary files pile up over time and can become surprisingly large. Disk Cleanup identifies and removes them safely.
How to clean system logs:
- Press Start and type Disk Cleanup
- Select your system drive (C:)
- Check categories like:
- Temporary files
- System logs
- Windows error reporting files
- Click OK → Delete Files
This clears:

It helps recover space while keeping Windows running smoothly.
Delete system error memory dumps
Memory dumps are created when Windows crashes—and some can be several gigabytes in size.
To delete error dumps:
- Open Disk Cleanup
- Click Clean up system files
- Check System error memory dump files and System error minidump files
- Confirm deletion
Why remove them?
- They’re only needed for advanced debugging
- They accumulate over time
- Most users never use them, yet they consume huge space
Clearing these can free multiple gigabytes instantly.
Clean up Windows installation files
After version upgrades or large updates, Windows keeps old installation files so you can roll back. These files can be massive—sometimes 20GB+.
How to remove outdated installation files:
- Open Disk Cleanup
- Select Clean up system files
- Check:
- Previous Windows installations
- Windows Update Cleanup
- Click OK
Important notes:
- You won’t be able to roll back to the previous version after this
- Performance and storage improve significantly
- Completely safe if your system is working fine
Disable hibernation to free gigabytes
Hibernation is a useful feature for laptops, but it comes with a major downside: it reserves a huge amount of disk space—often equal to 75% to 100% of your installed RAM. On systems with 16GB or 32GB of RAM, that’s a massive file sitting on your drive. Disabling hibernation is one of the quickest ways to reclaim gigabytes instantly.
Why the hibernation file takes huge space
When Windows hibernates, it saves your entire system state—including open apps, RAM contents, and background processes—into a file called hiberfil.sys.
- The file size is tied to your RAM (8GB, 16GB, 32GB, etc.)
- Even if you never use hibernation, the file still stays on your drive
- You can’t delete it manually because Windows locks it
- Disabling hibernation removes the file instantly
If you rely on Sleep mode instead of Hibernation, you can safely disable the feature without losing anything important.
How to safely disable hibernation via Command Prompt
Disabling hibernation removes hiberfil.sys immediately and frees up all the space it occupies.
Steps to disable hibernation:
- Press Start
- Type cmd
- Right-click Command Prompt → choose Run as administrator
Enter this command:
powercfg -h off- Press Enter
What happens next:
- Hibernation turns off instantly
- Windows removes hiberfil.sys
- You gain back several GB of storage immediately
To re-enable it later:
powercfg -h onDisabling hibernation is one of the highest-impact space-saving tricks—perfect for laptops with small SSDs or desktops that never use hibernate mode.
Move files to external or cloud storage
If your internal storage is running low, moving large files off your main drive is one of the easiest and most effective ways to free up space instantly. Whether you prefer physical storage or cloud solutions, Windows makes it simple to relocate files without losing access to them.
Transfer photos, videos, and documents to an external drive
External drives are great for offloading large personal files without deleting anything.
How to move files:
- Connect your external HDD, SSD, or USB drive
- Open File Explorer
- Select large folders like Pictures, Videos, Documents, or Downloads
- Right-click → Cut
- Paste them onto your external drive
Types of files best moved externally:
- Raw photos and edited media projects
- 4K/8K videos and recordings
- Old documents, school files, and archives
- Game backups and installers
Benefits:
- Frees huge amounts of space instantly
- Great for long-term storage
- Doesn’t change how Windows runs
Use OneDrive, Google Drive, or Dropbox for instant relief
Cloud storage lets you keep access to your files while removing them from your local disk.
How to move files to the cloud:
- Sign in to your cloud provider (OneDrive is built into Windows)
- Drag files into the OneDrive, Google Drive, or Dropbox folder
- Wait for upload to complete
- Delete the local copies
Cloud storage advantages:
- Instant access from any device
- Space savings without losing your files
- Automatic backups in case your PC fails
Great for storing documents, photos, school/work files, and anything you need frequently.
Enable “Files On-Demand” to reclaim space
Windows OneDrive has a powerful feature that lets you keep files visible—without taking up space on your SSD.
How to enable Files On-Demand:
- Click the OneDrive icon in the taskbar
- Go to Settings
- Select Sync and backup
- Enable Files On-Demand
Once enabled:
- Files appear in File Explorer as usual
- They download only when you open them
- You can right-click and choose Free up space to remove the local copy
Manage system restore and shadow copies
System Restore and shadow copies help you recover your PC after problems—but they can also consume several gigabytes of storage over time. By managing these features properly, you can reclaim space while still keeping your system safe.
Reduce the storage used by system restore points
Windows allocates a portion of your drive for storing restore points. You can lower the space limit without disabling protection entirely.
How to reduce restore point storage:
- Press Start, type Create a restore point, and open it
- Select your System drive (C:)
- Click Configure
- Under Disk Space Usage, drag the slider to reduce the size
- Click Apply
Recommended settings:
- 5–10GB for regular users
- 10–20GB for systems with frequent changes (developers, power users)
- Avoid setting it below 3GB, which limits restore usefulness
This keeps protection enabled while freeing space instantly.
Remove old restore backups
Windows stores multiple restore points, many of which may be outdated. You can delete all but the latest to reclaim space safely.
How to remove old restore points:
- Open System Restore settings (as above)
- Click Configure
- Choose Delete → Delete all restore points
- Create a fresh new restore point afterward
Benefits:
- Removes many gigabytes of old snapshots
- Keeps your system recovery clean and up to date
- Resolves issues caused by corrupted restore archives
This is completely safe as long as your system is working properly.
Balance safety vs. storage savings
When adjusting restore settings, consider how often you rely on them.
Choose higher storage if:
- You frequently install drivers or experimental software
- You’ve had system issues in the past
- You want multiple restore points for safety
Choose lower storage if:
- You rarely use System Restore
- You prefer full system backups instead (Macrium Reflect, etc.)
- You need emergency space immediately
Bonus: Use Storage Sense for auto cleanup
