13.6 GB free of 149 GB (drive provided by PgMusic when ordered several years ago)

I went to Properties and clicked on the "Disk Cleanup" button and was told that "You can use Disk Cleanup to free up to 0 bytes of disk space on EverythingPak (H:)." It goes on to say "Files to Delete: and indicates DirectX Shader Cache with 0 bytes, and Recycle Bin with j0 bytes. "Total amount of disk space you gain: 0 bytes".

And yes, going to my Desktop and right-clicking on "Recycle Bin" shows that this EverythingPak drive (my H:) is there.
