My approach to general files would be to attach them in the way we attach images, i.e. just store a filename (possibly with a hash) to the dive. Maybe one could obtain a representation of the file as a QImage, then we could display that in the pictures tab (renamed accordingly), for example a still image of a movie, otherwise we just show an icon (maybe the OS can provide one for the file type?) and upon double click invoke the open method of the OS (Mac has that, I am sure the others as well) on the file. Before, we might try some Qt ways of opening the file (like we do for images, we might as well for other video or audio files but we will have to rely on external programs for things like cartography files etc).

I am not sure what you are thinking of. Yes, the OS opens executable files (or the like like Subsurface.app) by executing them. Do you think we should prevent that? Should we keep a whitelist of harmless file types?

Best
