The fastest ways to free up storage right now

The quickest wins are usually temporary files, the Recycle Bin, and old downloads. Windows stores temporary files in a folder you can empty in seconds, your Recycle Bin holds deleted files until you permanently remove them, and your Downloads folder often fills with installers and documents you no longer need. Clearing these three places typically frees 5 to 20 gigabytes without touching anything important.

After that, the next layer is duplicate files, old backups, and applications you have stopped using. These take a few minutes longer to find and remove, but they often account for another 20 to 50 gigabytes. The slowest but most effective step is moving large media files — videos, photo libraries, or game installations — to an external drive or cloud storage, which can free 100 gigabytes or more depending on what you store.

Key Takeaways

  • Empty your Recycle Bin and clear temporary files through Settings > System > Storage > Temporary Files to recover several gigabytes in under a minute.
  • Use the Storage Sense feature in Windows 10 and 11 to automatically delete temporary files, old downloads, and Recycle Bin contents on a schedule you set.
  • Check your Downloads folder and Documents folder for old installers, archives, and files you no longer need — these often hold 5 to 15 gigabytes.
  • Uninstall applications you no longer use through Settings > Apps > Apps & Features, which removes both the program and its associated files.
  • Move large media files like videos, photo libraries, or game installations to an external drive or cloud storage to free the most space with the least risk.

Empty the Recycle Bin and temporary files

Your Recycle Bin holds every file you have deleted but not permanently removed. Right-click the Recycle Bin icon on your desktop, select Empty Recycle Bin, and confirm. This usually frees 1 to 5 gigabytes depending on how long it has been since you last emptied it.

Temporary files are separate and often larger. Open Settings, go to System, then Storage. Click Temporary Files and Windows will show you what it can remove — usually cache files, old update files, and temporary internet data. Select what you want to delete and click Remove Files. This step alone often frees 5 to 15 gigabytes.

If you want this to happen automatically, stay in the Storage menu and turn on Storage Sense. You can set it to delete temporary files and Recycle Bin contents every day, week, or month. This prevents the problem from building up again.

Clear out your Downloads and Documents folders

Your Downloads folder accumulates installers, PDFs, and files you meant to organize but never did. Open File Explorer, navigate to Downloads, and sort by date modified. Anything older than a few months is usually safe to delete — installers can be re-downloaded if you need them again, and old documents are often backed up elsewhere.

Check your Documents folder the same way. Look for old project files, duplicate copies of things, and anything you have moved to cloud storage already. Many people keep multiple versions of the same file without realizing it. Deleting duplicates and old versions can free 5 to 10 gigabytes.

If you are not sure whether a file is safe to delete, move it to a temporary folder on your desktop first rather than deleting it outright. After a week with no problems, you can delete the temporary folder. This gives you a safety net while you learn what you actually need.

Uninstall programs you no longer use

Applications take up space not just for the program itself but for supporting files, libraries, and cached data. Open Settings, go to Apps, then Apps & Features. Sort by size to see which programs use the most space. If you have not opened something in months, uninstalling it is usually safe.

Click the program name and select Uninstall. Windows will walk you through the removal process. Some programs leave behind configuration files or data folders even after uninstalling — these are usually small, but if you want a completely clean removal, you can manually delete the program's folder in Program Files or Program Files (x86) after uninstalling.

Games are often the largest culprits. A single modern game can occupy 50 to 150 gigabytes. If you have games installed that you no longer play, uninstalling them is one of the fastest ways to recover significant space. You can always reinstall later if you change your mind.

Move large files to external storage or the cloud

If you have a large photo library, video collection, or archive of old projects, moving these to an external drive or cloud storage frees the most space with the least risk. External drives are inexpensive — a 2-terabyte drive costs $50 to $80 — and they keep your files accessible without taking up space on your PC.

To move files, plug in an external drive, open File Explorer, and drag your folders to the new drive. Windows will copy them. Once the transfer is complete and you have verified the files are there, you can delete the originals from your PC. For cloud storage, services like OneDrive, Google Drive, or Dropbox let you move files to their servers and access them from anywhere. OneDrive is built into Windows and offers 5 gigabytes free; other services offer similar amounts.

A common strategy is to keep recent files on your PC and move anything older than a year to external storage. This keeps your drive fast and responsive while preserving everything you might need later.

Check for duplicate files and old backups

Windows creates backup files, restore points, and duplicate copies of things without always telling you. Open File Explorer and search for large files by going to the search box and typing size:>100MB to find everything over 100 megabytes. Scroll through the results and look for duplicates or backups you recognize.

System restore points are another hidden space consumer. Open Settings, go to System, then About, and click Advanced System Settings. Go to the System Protection tab and click Configure. You can reduce the amount of space Windows reserves for restore points or delete old ones. Be cautious here — keep at least one recent restore point in case you need to recover from a problem.

If you have been backing up your PC to an external drive or cloud service, old backup files can accumulate. Check your backup location and delete backups older than a few months. Most backup software lets you set a retention policy so old backups delete automatically.

Use Disk Cleanup for a guided approach

If you prefer a guided process, Windows includes a built-in tool called Disk Cleanup. Press the Windows key, type Disk Cleanup, and open it. The tool scans your drive and shows you categories of files it can remove: temporary files, old Windows installations, recycle bin contents, and more. You can select which categories to delete and click OK.

Disk Cleanup is less powerful than manually going through Storage Sense and your folders, but it is a good option if you want Windows to handle the decisions for you. It typically frees 2 to 10 gigabytes depending on your system.

For a more thorough scan, you can also use the Storage Sense feature mentioned earlier, which is the newer version of Disk Cleanup and includes more options for automatic cleanup on a schedule.

Frequently Asked Questions

Is it safe to delete everything in my Temp folder?

Yes, the Temp folder holds temporary files that Windows and programs create while running. Deleting them will not harm your system. Windows recreates them as needed. Use the Storage Sense tool in Settings rather than manually navigating to the Temp folder, because Storage Sense knows which files are actually safe to remove.

What happens if I delete a file from my Downloads folder?

It goes to your Recycle Bin, where you can recover it for up to 30 days (depending on your settings). If you empty the Recycle Bin, the file is gone permanently. For this reason, it is safe to delete old downloads — if you need an installer again, you can download it once more from the original source.

Can I move my entire Documents folder to an external drive?

Yes, but you need to be careful about how you do it. Copy the entire Documents folder to your external drive first, verify all files are there, then change your Documents location in Settings. Go to Settings > System > Storage > Advanced Storage Options > Where New Content is Saved and point Documents to the external drive. This way, new files save there automatically.

How much space should I keep free on my PC?

Windows performs best when you have at least 10 to 15 percent of your drive free. If your drive is nearly full, Windows slows down because it cannot create temporary files or cache data efficiently. If you are consistently running low on space, moving large files to external storage or upgrading to a larger drive is worth considering.

Will clearing space make my PC faster?

Freeing up space helps your PC run faster, but only if your drive was nearly full. Once you have 10 to 15 percent free, clearing more space will not noticeably improve performance. The main benefit of clearing space is preventing slowdowns and making room for new files and updates.
