Why make this F746 or STM32 specific, FatFS is platform agnostic.
Is there an issue with this example?

>>ST uses unfamiliar commands for reading all files in a directory.
Ok, but what does that mean, unfamiliar to them, to you, others practiced in the art?

Some settings or plug-ins at your end, this isn't an issue for 99.99% of users here. If it becomes sufficiently annoying, then change your behaviour.
