We're sharing a file via my local NAS with Synology in a win64bit (my end) / mac (Mojave) environment, so Nic only sees the Synology interface. We don't do workgroup referencing as we've both had problems before and don't want to waste more time on that. We only work on a file one at a time.
The problem is the VW file cannot retain linked references from one hard-drive to another.
The issue is one project with a lot of image rasters* (mostly .jpg) which I reference to at my end to keep file size at a minimum. At Nic's end files open fine, but a save at Nic's end changes the link locations to Nic's machine and I have to relink on my machine.
I'm considering trying to have Nic's mac reference a copy of the files off a Dropbox (and link the dropboc files back to my NAS, but still trying to see if that's viable).
No, that didn't work.
I've seen this forum post which doesn't look hopeful and seems to add needless complication.
