It may mean an appropriate program that can handle that type/format file is not installed.

Or OP trying to run downloaded file without first unblocking it?

When are you getting that, in a Browser or a program on the computer? Have you run Error Checking against that C: drive? Right-click it and Properties, Tools.

I open .mov files [Apple's format] in VLC/Video Lan.

What program did it work with? I haven't tried the .mov type files in Microsoft's movie/video program, always use VLC.
Official download of VLC media player, the best Open Source player - VideoLAN

thank you, the player, worked
