Do you want to access your PhotoStructure library on two or more desktops or servers?
First read this article:
There are several ways to set things up.
You can run PhotoStructure on a central computer or NAS, push new files to that computer (either via network shares, software like Resilio Sync, or built-in backup software), and then set up remote access
You can put your library on an external drive, install PhotoStructure on each computer, copy new, unique files (via automatic organization onto the external drive, and once the import is compete, move the drive to the next computer and import from there.
There’s really only one caveat to be aware of: a single PhotoStructure library can’t be opened by multiple computers simultaneously.
