> I still have tonnes of .rar. Exclusively for legacy reasons (you can google why .rar exists), sure i could spend the time extracting everything, or continue using Kodi which is my current solution.
I don't understand why you'd want to keep media files in .rar, unless you are part of scene distribution.
It's not like ROM emulation, where there's tangible savings to be had storing the individual ROMs in a compressed format.
