I got a warning while copying files to my Apollo Cloud that the disc was almost full and certain features would not work. In fact the dashboard claimed that the disc was 80% full, presumably with 500GB remaining.
I deleted one of the failed USB transfer's folders… the file system on the Apollo doesn't really tell the user enough to compare original and copy folders other than counting files and folders manually.
This folder has now disappeared from the files window but the trash view/tab/window says that the trash is empty. Shortly afterwards, I got a warning dialog to say that files could not be deleted.
The disc usage indicator still says 80%.
Nothing in the trash, folder disappeared but still no change to the available disc space?
It's taken 9 hours to copy 175GB so there's time for a reply from Promise before anything significant happens… since the transfer is likely to take about 3-4 days.
