How to Free Up Space on Your PC for More Games
Modern AAA games routinely demand 80 to 150GB each, and it doesn’t take many of them before even a large SSD feels cramped. The good news is deletion isn’t your only option. Identifying what’s actually eating your space, moving what doesn’t need your fastest drive, and clearing out forgotten clutter can free up serious room without gutting your library. Here’s how.
1. Uninstall What You Haven’t Touched
This delivers the biggest instant win. On most gaming PCs, installed games and their associated files account for 60 to 80% of total used storage, and a single modern title with all its DLC and patches can easily exceed 200GB on its own. Look for anything you bought on sale but haven’t launched in six months or more. On Steam, your progress and achievements save to the cloud, so reinstalling later brings everything right back exactly where you left it.
2. Find Out What’s Actually Using Your Space
Don’t guess, check. Windows Storage settings break drive usage into categories, separating installed apps from temporary files, documents, and system data. For a deeper look, free tools like WinDirStat or TreeSize scan your entire drive and show you the largest files and folders at a glance, including duplicate files you may have accidentally saved twice without realizing it.
3. Enable Storage Sense
This is a free, set-and-forget feature that quietly does maintenance for you. Go to Settings, then System, then Storage, and toggle on Storage Sense. It automatically clears temporary files, empties your Recycle Bin on a schedule, and removes old downloads without you having to remember to do it manually.
4. Run Disk Cleanup for a Deeper Sweep
Search for Disk Cleanup in your Start menu and run it against your main drive. This catches system files, old update leftovers, and temporary data that Storage Sense alone sometimes misses, particularly after a major Windows update.
5. Check Your Downloads, Videos, and Screenshots Folders
These folders quietly accumulate huge amounts of forgotten clutter old installers, video captures, and screenshots you’ll never look at again. Sort by file size within File Explorer and delete anything over 500MB you no longer need. Smaller files generally aren’t worth the time it takes to hunt them down.
6. Use Compression on Games You’re Not Actively Playing
Free tools like CompactGUI can shrink installed game files using Windows’ built-in NTFS compression, without deleting anything. This won’t work miracles on every title, but for games you want to keep installed without them eating full-size space, it’s a genuinely useful middle ground between deleting and keeping.
7. Set Up a Two-Drive System
The optimal 2026 setup pairs a fast NVMe SSD for Windows and your actively played games with a larger, more affordable SSD or drive for your broader library. A 2TB secondary drive can comfortably hold 15 to 25 modern AAA titles, giving your active games the speed boost while everything else sits ready without hogging your primary drive.
8. Move Games to External Storage
If you’re using an external drive, stick to USB 3.2 Gen 2 or better with a proper external SSD running modern games through USB 2.0 isn’t a good experience for anyone. For straightforward game storage rather than your primary system drive, the read-speed difference between NVMe and SATA matters far less than raw capacity and reliability.
The Bottom Line
Running low on storage doesn’t have to mean choosing between your games and your personal files. Start with uninstalling your unused backlog for the fastest results, layer in Storage Sense and Disk Cleanup for ongoing maintenance, and consider a second drive if storage keeps becoming a recurring headache. A little regular upkeep goes a long way toward avoiding that full-drive scramble right when a new release drops.
FAQs
Will I lose my progress if I uninstall a game to free up space?
No, on most platforms. Steam and similar services save your progress and achievements to the cloud, so reinstalling brings everything back.
What’s the fastest way to find what’s using the most storage?
Free tools like WinDirStat or TreeSize scan your entire drive and show you the largest files and folders instantly.
Does Storage Sense actually make a noticeable difference?
Yes, over time. It automatically clears temporary files and old downloads on a schedule, without you having to remember to do it.
Is a secondary drive worth adding for game storage?
Yes, if you have a large library. A 2TB secondary drive can hold 15 to 25 modern AAA titles, keeping your primary SSD reserved for active games.
Can I run modern games directly from an external USB drive?
Yes, but only with USB 3.2 Gen 2 or better and a proper external SSD. Avoid USB 2.0 for current-gen games.
