Clearing disk space on Windows 11 can feel like a chore, especially if your PC starts acting sluggish or giving you low storage warnings. Sometimes, just deleting a few files isn’t enough; you need a more thorough clean-up that involves both removing unnecessary files and uninstalling apps you no longer use. Doing this regularly not only frees up space but also keeps the system humming along nicely. It’s kinda funny how unorganized files can bog down performance — but, of course, Windows makes it a pain to find and remove the junk without a guide. So, here’s a shot at some tried-and-true ways to get that disk back in shape.
How to Clear Disk Space on Windows 11
Open Disk Cleanup — The easy first step
If Windows 11’s low disk space alert has you worried, head straight for the built-in Disk Cleanup tool. On some setups, it’s hidden a few clicks away, but it’s worth hunting down. Just click the Start button, type “Disk Cleanup” into the search bar, and open the utility. Sometimes, it doesn’t show up immediately, so if that happens, digging through Settings > System > Storage and clicking on Temporary files can do the trick. On Windows 11, you can also access this via Settings > Storage > Temporary files to see what’s taking up space. Once open, select your main drive — probably C: — and hit OK. It’ll spend some moments calculating what’s trash, which is normal; just give it time.
Select the right files to trash
This is the part where you get to play detective. Disk Cleanup pops up with a list of file categories like temporary files, system cache, and Internet cache. If you’re like most folks, checking most boxes is tempting, but be careful — some temporary files *might* be useful for apps. On one setup it worked to just check everything, on another… not so much. Common safe bets are cache files, thumbnail caches, and old Windows update leftovers. When you’re ready, click OK and then Delete Files to confirm. This helps clear out all that clutter that’s just sitting there, taking up space without any real purpose.
Uninstall unused programs via Settings — Because some apps just hang around
Ever downloaded a game or app, then forgot about it? Well, those ‘forgotten’ programs pile up. Go to Settings > Apps > Installed Apps (or Apps & Features) to see everything installed. Uninstall what you don’t need anymore — especially big ones like old Photoshop versions or game installers. Removing these can free up a decent chunk of disk space and make your PC boot faster. A heads-up: some apps might be tricky to remove, especially from third-party sources. If you run into trouble, try launching the uninstall via the app’s folder or using a third-party uninstaller.
Use Storage Sense to automate the cleanup in case manual isn’t enough
This feature is kinda weird but super handy. It automatically deletes temporary files, downloads, and stale system files when stuff gets full. Head to Settings > System > Storage, and turn on Storage Sense. You can specify how often it runs — daily, weekly, etc. — and what it should clean. Definitely helps if you wanna keep things tidy without constantly poking around manually. Not sure why it works sometimes, but on certain machines, enabling Storage Sense kicks in and tidies things up without fuss.
Extra tip: Move large files or backups to external drives or cloud
Got a big collection of videos or photos? Consider moving them to an external SSD or cloud services like OneDrive, Google Drive, or Dropbox. It’s not just about free space, but also about reducing the clutter on your main drive, which can boost overall system responsiveness. Sometimes, just shifting a few hundred gigs frees up enough space to breathe again.
Tips for Clearing Disk Space on Windows 11
- Regularly run Disk Cleanup — make it a habit.
- Use external storage for large media files.
- Enable Storage Sense for auto-cleanups.
- Move infrequently used files to cloud storage.
- Be cautious with system files — don’t delete something you’re not sure about.
Frequently Asked Questions
How often should disk cleanup be performed?
Honestly, if you’re not a heavy gamer or content creator, once a month is enough to keep things in check. More often if you notice your PC slowing down or getting storage warnings.
Can deleted files be recovered after Disk Cleanup?
Once Disk Cleanup is done and files are gone, they’re basically gone for good — no easy undo. So, double-check what you’re deleting, especially if it’s stuff like system cache or old update files.

More room = less stress on your drive. It can help Windows optimize better and might shave a second or two off startup times.

It’s a Windows feature that automatically clears out junk files and temporary files. If you’re forgetful or just want less maintenance, enabling it is a good move.
Third-party tools — worth it or not?
Plenty of cleaner apps are out there, but be selective. Stick to reputable ones like CCleaner or BleachBit. Still, Windows’ built-in tools cover most needs.
