I purchased 200G of iCloud drive storage to keep my 128G MacBook Air running and not clogged up. Every file I move into the iCloud drive folder doesn't clear space on my HD, even if it says it completed the transfer, and when I delete files from iCloud drive space clears up on Mac HD. Are iCloud drive files saved on the SSD in any way? And what should I do to clear space on my SSD beside moving to DropBox?
