Storage Sense can automatically free up drive space for you by getting rid of items that you don't need, like temporary files and items in your Recycle Bin. Here’s more info on how it works and how to set it up to meet your needs.

Content from the Recycle Bin will be deleted by default after some time, but items in your Downloads folder and OneDrive (or any other cloud provider) will not be touched unless you set up Storage Sense to do so.
