I recommend trying the built-in Disk Clean up tool built into windows 10.
- Open up the Settings App for Windows 10.
- Click on "System".
- Click on "Storage"
- Click on "Temporary Files" for the C Drive.
- Make sure that "Delivery Optimization Files" is checked.
- Click "Remove Files".
- Wait for dialog to finish. This can take a long time depending on how many files are being removed.
does this really work? i need to reinstall the game just to get a link code for steam but i dont wanna install it if its going to steal my hard drive space again
