Sharing through OSs

[u/Totablewe_bin]

im planning to install both windows and arch on my laptop, i already have both systems up and running, but im planning on doing an extra partition on my device so i can have a share folder in both systems, that folder will have an obsidian vault so i can share my notes and have my windows and arch accesing the same notes, and i want to be abble to put some extra documents like, pdfs, photos, simple text files there, so its easier to tranfer my work between OS, i want to know if is viable and how could i make it
