You have several options for maximizing PC storage space:
Configure Storage Sense to work as frequently and in as many places as possible.
Look for large media files, such as videos, to clear off of your machine, either by moving them to the cloud or another storage device or by deleting them.
Frequently clean up your Downloads folder to remove unnecessary files.
Purchase an external USB storage device to hold large files.
Start using a cloud storage drive for media files and personal documents.
Upgrade your old storage to a new drive that provides significant excess space.
