How to install game update files on folium?

The game was successfully running in folium, but failed to install the update file.

Referring to this post, I checked that the game installation and update file was installed and applied in Citra PC version, but moving this back to folium failed.

I successfully moved the game file from citra to the cytrus -> roms file in polium, and the game ran but the update didn't apply.

What am I missing? Also, is there a way to install the update file directly within folium?
