38 GB of the used space is already in the Recycle Bin. Emptying it in Explorer frees that space.

A demo clean of the two Clean rows on the drive in the Overview screenshot. Nothing ran on your PC to make this page.

37.9 GB moved. App Caches and Dev Tools read 0 bytes, and the sidebar's Trash card goes from 160 MB to 38 GB.
Nothing freed yet. Used and free space stay at 247.8 GB and 7.6 GB until you empty the Recycle Bin in Explorer. Empty it, and free space goes to 45.5 GB.
Nothing else moved. Large Files and Installed apps sit under Review and are only ever picked one at a time.
