ROM Hack Question Save Trimming?

[Niko_of_Death]

Would it theoretically be possible to "trim" save files that have very high reserved save sizes with little actual save data being used? For example, Dragon Quest Builders reserves 703MB for save data, but, in my save, only 27MB is actually being used, meaning 676MB of my system storage is being taken up by placeholder space.

If they have fixed size in exefs while reading file, then no.
