[GNC] Linked file paths when copied to a different computer

[Chris Skudder]

I'm treasurer of our church and keep the books on GnuCash.
It's a terrific solution, kudos and my heartfelt thanks to the dev's and 
the whole team.

I do my work remotely on my own computer (Xubuntu 22.04, GnuCash 5.9 
Flathub). (I also keep a couple other GnuCash books on my machine.)

I back all my church files up to a Windows computer at the church. It 
has the same version of GnuCash installed. I don't enter transactions on 
the church computer, it's used only as "read only" for auditing.

I'd like to fix or change the paths to linked files on the Windows 
machine so that they open correctly- this would obviously make auditing 
much easier, faster, etc.

I know about Edit > Prefs > General > Path Head for Linked Files 
Relative Paths - but it doesn't make sense to use it in Xubuntu because 
I keep other books with the same Gnucash application, for which the 
supporting documentation is in different folder locations.

But trying to use that on the Windows machine, I can't get the linked 
file paths working on that one. I seem to have some distant memory of a 
way to find and fix broken file links (or maybe that was a different 
application). All the linked files are in no more than 2 or 3 
directories, so a "global replace" of the Xubuntu file paths with the 
Windows paths would do it.

What else might I be missing?

Thanks in advance,
Chris
