Hello there, I recently started backing up my collection and when I went to play some of my files that I had downloaded from 2019 about 6/10 will play fine but the rest just seem to open VLC as if it were default. There were only 80gb of space left but its just sat in a closet for 2 years occasionally being plugged in to locate a file. Does anyone know a cause for this such thing? The file sizes say they are complete under properties. Is there any way to repair this?
