After a copy that failed due to "not enough space on the disc", I cleared enough disc space and repeated it, but then got a false "not enough space on the disc", confirmed false by the fact the same copy in Explorer then succeeded - see attached.
Exit, relaunch, retry succeeded.
Also, it would be nice if the error message IDed the disc.
