I’m already doing something similar to this, and argentum pretty much explained it. Here is my take on it using just 1 vault:
- Master-Vault:
- .obsidian
- PKM
- Work & Projects
- Both
On your work computer, remove the PKM folder from sync, then on your non-work computer remove the Work & Projects from sync. Make sure they don’t exist locally (delete after you unsync) so that you can’t link between PKM and the Work folder.
Even better, you don’t even need the both folder, as anything in the master vault is synced between two systems.
