Win11
In the settings, I clicked the checkbox to show "Other files". It worked properly: it showed other files not related to graphics and movies. I didn't need it anymore, so I unchecked that option. The file list went back to its previous state. To my surprise, when I restarted the program, I saw these other files again. When I just went to another folder and came back, everything was back to normal.
