Getting rid of space hogs on Windows 11 is kind of weird, but it’s doable. Sometimes, the system just accumulates junk without asking, and pretty soon, the disk space is getting tight. If you’re tired of constantly seeing that “low disk space” warning or your PC slowing down, this guide should help you clear out enough to keep things ticking smoothly. The idea is to target all those hidden temp files, unused apps, downloads, and large files clogging up your drive. Doing this regularly isn’t just about freeing space — it can help your system run faster and more responsive, especially if you have an SSD.
Just a heads-up, some steps might seem a bit repetitive, but on one machine it worked the first time, on another, not so much. Because Windows has to make it harder than necessary sometimes. Anyway, here’s the lowdown on how to clear space without risking important stuff, with some tweaks along the way.
How to Free Up Space on Windows 11
Method 1: Run Disk Cleanup
This is one of those classic Windows tools, and honestly, it still works pretty well. It helps you delete all those unnecessary system and temp files that pile up over time. It’s especially useful if you want a quick cleanup without messing around too much. Head over to the Start menu, then type Disk Cleanup and open it up. When it asks which drive, usually C:, just pick it. You’ll see a list of files it can delete — system cache, temp files, old logs, maybe even previous Windows updates if you’re lucky. Hit OK and let it do its thing.
Pro tip: for an even deeper cleanup, click Clean up system files inside Disk Cleanup. That’ll scan again with admin rights, giving you options to delete even more junk. Some users report that Disk Cleanup can sometimes miss files, especially if it’s been a while, so don’t expect miracles, but it’s a solid first move.
Method 2: Enable Storage Sense
This handy feature in Windows 11 automatically tidies up unnecessary files in the background. If you want to stop worrying about manual cleanup, turn it on. Go to Settings > System > Storage. Then find Storage Sense and toggle it on. You can customize what it deletes — like temporary files, items in your Recycle Bin, and even files in your Downloads folder after a certain period. When set right, it keeps your disk lean without you lifting a finger. Sometimes, I’ve noticed that activating Storage Sense catches a lot of leftover files that would otherwise sit there forever. On some setups it failed the first time, then worked after a reboot or a toggle restart, so don’t worry if it doesn’t seem to work immediately.
Method 3: Uninstall Unused Apps
This one’s straightforward but effective. Over months, we all forget about those random apps we installed once and never opened again. Head to Settings > Apps & Features. Here, sort by size or last used date, and start removing the big offenders. Apps like old games, utilities, or trial software that you’re never going to use anymore — deleting these frees quite a bit of space quickly. Just be cautious not to uninstall anything critical. Sometimes, Windows doesn’t delete all app files cleanly, so if an app leaves behind residual data, use an app-specific cleanup or third-party tool like WinDirStat to identify those space hogs.
Method 4: Move Files to External Storage or Cloud
If you’ve got high-res photos, videos, or backups eating up the space, consider transferring them. External HDDs or SSDs work great, and there are also cloud options like OneDrive, Google Drive, or Dropbox. Moving large media files off your main drive can free gigabytes in seconds. It’s a good way to keep your internal storage lean, especially if your PC isn’t big on expandable drives. A little side note: sometimes Windows flags files as large or bulky, but it’s surprising how much space just moving them elsewhere helps. This also acts as a backup if something ever goes sideways.
Method 5: Clear Downloads Folder & Empty Recycle Bin
Surprisingly, the Downloads folder and Recycle Bin are the usual suspects for hidden clutter. Open File Explorer, head over to Downloads, and delete anything you no longer need. Don’t forget to go to the Recycle Bin and empty it. Without doing this regularly, these can silently consume dozens of GBs. Not sure what’s safe to delete? If you haven’t opened a file in months, it’s probably okay. But double-check if you’re unsure — because once deleted, there’s no turning back unless you have backups.
After all this, your free space should start creeping back up. Your PC might run snappier, and that nagging space warning may disappear for a while. Sometimes, a reboot helps all these changes settle in.
Tips for Keeping Your Storage Under Control
- Check your storage usage periodically inside Settings > System > Storage.
- Set Storage Sense to run automatically on a schedule — daily, weekly, whatever works for you.
- Use cloud storage for files you rarely access. It’s a good way to keep local space free but still have them accessible.
- If you don’t use hibernation, disable it to save space. Navigate to
cmdas admin, then runpowercfg -h off. - Third-party tools like CCleaner or BleachBit can help, but grab them from reputable sources—Windows loves to make it tricky sometimes.
Frequently Asked Questions
How often should Disk Cleanup be run?
Best to run it once a month if you want to keep things tidy, but more frequently if you install/uninstall stuff a lot.
Does uninstalling apps free up space right away?
Yep, as long as no residual files are left behind, you get the space back instantly after uninstall.
Can Storage Sense manage external drives?
Sort of. It mainly handles internal storage, but it can prompt you to offload files to removable drives or cloud if configured properly.
What files are safe to delete?
Anything in Temp folders, Downloads (if you’re sure), and Recycle Bin, generally. Use Disk Cleanup for automatic safety, or review files manually to avoid deleting something needed later.
Deleting files from Downloads — any risks?
Mostly safe, but if you’re unsure whether a file is still needed, move it somewhere else first. No point deleting something important permanently if you’re not sure.
Summary
- Run Disk Cleanup periodically.
- Activate Storage Sense for automation.
- Uninstall unused apps.
- Shift large files to external storage or cloud.
- Clear out Downloads and Recycle Bin often.
Wrap-up
Managing storage on Windows 11 isn’t some complex science — it just takes a bit of regular upkeep. Clearing out the junk files, removing unused apps, and keeping an eye on big files can make a noticeable difference in how your PC feels. On a practical level, it’s about slowing down those annoying pop-ups and keeping everything humming along. If this gets one update moving, mission accomplished. Fingers crossed this helps — just remember, a little maintenance beats letting things pile up forever.
