OS 10.12.6

I downloaded 7 movies and transferred them into my Lacie HD. Showing them as icons, (1) does not appear and showing them as listings, (2) do not appear one of which is the one missing as an icon.

I have dragged them into the HD several times and each time being told they are already there.

I can play them both from the desktop.

Anyone know why this is happening?
