[Feature Request] Allow to display file size in KiB, MiB, GiB, etc.

Currently, MaterialFiles display file size in KB (10^3 B), MB (10^6 B), etc. But I would like to see file size in KiB (2^10 B), MiB (2^20 B), etc., which matches what I see on my PC. I do not expect the changing of default behavior, a setting item is sufficient for me.

I do not want to discuss "which one is right", but it is always good to let users choose what they want in the setting.
