@Karl . Just wondered if you overlooked @Aravisian 's left field suggestion to use multi-platform cloud storage for your (maybe often used) shared Windows and Zorin workfiles, like he mentioned at bottom of this post: File explorer – starred files - #6 by Aravisian
A Mega account may be an option for you as it provides a reasonable amount of stoage in the free plan. Not just me, others on here have also endorsed it.
However, the disparity between Win and Zorin filesystems is a problem for those wishing to open and work on files in both OS.
