In modern flight simulators, "video" assets generally serve one of two purposes:
A. Flight Instruction / Tutorials
Older iterations of flight sims often included video files ( .avi, .ogv, or proprietary .bin wrappers) that played during interactive tutorials. If this binary is labeled "unused," it is likely a remnant of an old tutorial system that has since been replaced by text-based checklists or scripted JavaScript tutorials within the simulator.
B. Texture Pre-caching Sometimes "video bin" refers to a sequence of frames used for animated textures (like a moving map display or a weather radar) stored in a binary format for faster I/O streaming. If the feature was deprecated but the file remained in the repository, it becomes an "unused binary."
Finding an unused binary in an open-source project like FlightGear is common due to the "Breakage Aversion" principle in software development. fgoptionalunusedvideosbin link

Have you ever searched for a way to clean up “unused videos” and stumbled upon strange terms like fgoptionalunusedvideosbin link? You’re not alone. That exact string doesn’t point to a real Windows feature, but it hints at a common need: freeing up space by removing video files you no longer need.
In this guide, I’ll show you legitimate, safe methods to locate and delete unused videos — without downloading suspicious “optimizer” tools. In modern flight simulators, "video" assets generally serve
