How to Free Up Storage Space for Large PC Games

Check the drive that is full, then move a game, uninstall one you no longer need, or clear eligible Windows files. Protect local saves before changing installations.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

To make room for a large PC game, first check which drive is full. Then move an installed game to another drive, uninstall one you do not need right now, or use Windows Storage Sense to remove eligible temporary files. Use the game launcher’s controls rather than deleting folders at random, and check save-file handling before removing a game.

Find out which drive needs space

In Windows, open Settings > System > Storage to see how the system drive’s space is being used. To inspect another drive, open Storage settings’ advanced options for storage on other drives. In Steam, go to Steam > Settings > Storage to see library drives and the games installed in each library.

This helps distinguish a full C: drive from a full game-library drive. If your games are on another drive, cleaning C: may not create room for a game installed there; check the destination drive before choosing what to remove. Game size varies with updates, language packs, optional content, and other files, so the amount you can reclaim depends on your installation.

Choose the right way to make room

Option Best when What it does Trade-off
Move a game You want to keep it installed and have another usable drive. Relocates the installation to another library. The destination needs enough free space; moving does not reduce the game’s size.
Uninstall a game You do not need it installed right now. Removes its installed files from that drive. You may need to download it again later. Save files may be stored separately.
Use Windows cleanup The system drive contains eligible temporary files or Recycle Bin contents. Removes selected Windows-managed files. It does not uninstall games, and you should review what is selected.
Add another drive You regularly run out of room and need more library capacity. Provides another possible location for game installations. Check capacity, connection and port compatibility, and where the library will live.

Move a Steam game to another drive

If you want to keep playing the game without downloading its full installation again, move it through Steam. Steam describes its library folder as containing installed games on disk. Its instructions cover creating a library on another drive and moving installed games: Steam Support: Moving a Steam Installation and Games.

Western Digital 1TB P40 Game Drive SSD - Up to 2,000MB/s, RGB Lighting, Portable External Solid State Drive , Compatible with Playstation, Xbox, PC, & Mac - WDBAWY0010BBK-WESN
  • Customize your drive’s RGB lighting with the downloadable WD_BLACK Dashboard (Windows only) to show off your style and make every play personal.
  • Kick loading into overdrive with a USB 3.2 Gen2x2 interface and speeds up to 2,000MB/s. (Based on read speed. 1 MB/s = 1 million bytes per second. Based on internal testing; performance may vary depending upon host device, usage conditions, drive capacity, and other factors.)
  • Compatible with PlayStation 5 and Xbox Series X|S consoles. {Compatible with PlayStation 4 Pro or PS4 with system software version 4.50 or higher, PlayStation 5 (Play and store PS4 games; archive PS5 games), Xbox One, and Xbox Series X|S (Play and store Xbox One games; archive Xbox Series X|S games).}
  • Keep more of the latest and largest titles installed and ready to launch with capacities of up to 2TB. (1TB = 1 trillion bytes. Actual user capacity may be less depending on operating environment.)
  • Built with WD_BLACK toughness thanks to a shock-resistant structure, this durable drive can survive a drop of up to two-meters.
  1. Connect or select the drive you want to use, and make sure it has enough free space for the game.
  2. In Steam, open Settings > Storage. Add or select a library location on the destination drive.
  3. Select the game in Storage and choose the move control, then choose the destination library.
  4. When Steam finishes, launch the game to confirm it works. If files appear damaged or missing, use Steam’s file-verification procedure; it checks and may repair the installation, but does not free space. See Steam Support: Update & Installation Issues.

A move changes where the installation lives; it does not make the game take up less space overall. If your PC has no convenient internal capacity, an external SSD may be an option, provided its connection works with your computer and it has sufficient capacity. No particular model, interface, or speed is established here.

Uninstall a game you do not need installed

Use the game launcher’s uninstall control, or Windows’ app removal controls when appropriate, and then check the affected drive’s available space. Launcher-level removal helps keep the launcher’s records consistent. Steam warns that uninstalling Steam removes installed game content; its instructions for preserving the steamapps folder apply to removing the Steam client, not uninstalling one game. Follow Steam’s guidance if you intend to remove the client: Steam Support: Uninstall Steam.

Use Windows cleanup for non-game files

Storage Sense can remove selected temporary files and Recycle Bin items. Open Settings > System > Storage, review the Storage Sense options and file selections, and only enable automatic cleanup if its schedule and selections suit you. Microsoft says Storage Sense operates on the system drive. Its defaults do not clean Downloads or OneDrive, but settings can be changed, so inspect them rather than assuming those folders are always excluded. For details, see Microsoft Support: Manage drive space with Storage Sense and Microsoft Support: Free up drive space in Windows.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Storage Sense is for eligible Windows-managed files, not a substitute for moving or uninstalling a game. Do not assume it cleans non-system drives; use Windows’ storage controls to inspect those drives.

Protect your saves and avoid folder mistakes

A save file is not necessarily part of the game installation. Steam notes that third-party games without Steam Cloud saves may keep saves in DocumentsMy Games, while some developers use a different location. Before removing a launcher or manually changing game folders, check the game publisher’s instructions and back up important local saves. Steam’s guidance on moving installations also discusses possible save locations: Steam Support: Moving a Steam Installation and Games.
