When it’s done, you will be presented with a screen like the one below. Use the visual guide to find large files and folders taking up space on your hard drive. Or use the file type or folder breakdown to locate what is taking most of your room.

Since it doesn’t differentiate between system and user files, it’s easy to see just how large your photos or download folders are.


Upgrade Your Storage

If you’ve followed our guide and still can’t free up enough space, don’t fret! It’s never been easier or cheaper to upgrade your computer hard drive with one that has more room. Many consumer SSD brands will come with free software that can be used to move everything to your new hard drive.

If upgrading your internal hard drive isn’t an option, external hard drives are another excellent option to store music, videos, and pictures. This will save space on your faster internal drive for programs and games.
