Apple has been adding bugs and destroying usability at a rapid clip for several years now, the worst offender being OS X Yosemite, whos bugs continue to add small burdends to my work every single day. There are just too many issue to report on, so I sigh and just 'deal'.
But this one is obvious so why not show it. It’s one example of a litany of behaviors that have mushroomed in OS X; areas that worked for years going wonky.
Note the zero-sized files. But they are not zero in size as the Finder’s own Get Info window shows! Local file system (not a network volume). In a similar vein, a Finder 'move' operation leaves files behind about one time in 10, and sometime doesn’t work properly at all (reverts to a copy instead of a move), due to performance bug (since 10.10.4) that delays interactive use by the better part of a second.
