I have about 14GB of ScreenFlow saves that I wish to delete because they are no longer needed. I move the first to Trash, then clicked on "Empty." After I do this, I get this error: "The operation cant be completed because some items had to be skipped. For each item, choose File > Get Info, make sure Locked is deselected, and then check the Sharing & Permissions section. When you are sure the items are unlocked and not designated as Read Only or No Access, try again." I already went through all of them. They are all unlocked and I have Read & Write permissions. When I try to Secure Empty Trash, it stops at 1/4 of the way through the loading bar thing.
