If your PC is running low on storage, here are a few ways to free up some drive space.
If you have storage sense turned on in Storage settings, Windows can automatically free up space by getting rid of files you don't need, like temporary files and stuff in your recycle bin. Or, you can delete them manually.
If you have photos, music, or other files that you want to keep but don't use very often, consider saving them to removable media, like a USB drive. You'll still be able to use them when the drive is connected, but they won't take up space on your PC.
Instead of saving all your new files to the same drive, save some of them to a different drive.
If you've updated to the latest version of Windows 10, save space by turning on OneDrive Files On-Demand. You'll be able to get to your OneDrive files from your PC without having to download them all. See Learn about OneDrive Files On-Demand for more info.
