Windows 8.1, restarted many times - explorer will not delete. effort sometimes crashes w. explorer. Eracer will not delete at boot.
Background: A Cobian backup failed leaving a partial zip file of about 250 gig! (since then I have split the tasks!). I attempted to delete this zip file (using TeraCopy) and got most of it. However, it left behind, unable to delete, 170 small files in several folders totaling about 12 mb that all produce the same or very similar error message ( see attachment). I attempted to use Eraser to remove it at boot-time but that also failed.
How can I delete this zip file remnant?
