If you import the photos a second time, you will end up with duplicate photos, so instead you should ‘fix’ (or ‘consolidate’) the existing photos. Simply, this just means to update the path to the photos stored in the database. In most cases this should work mostly automatically, however, the fact that you’re switching from Mac to Windows with a different file system might make it more difficult.
Anyway, first, I’d try to move the photos the conventional way. To do this, just open the project on the target computer and select any photo for consolidation like it says in the documentation: Tropy will prompt you to locate the photo in the shared drive and, once you’ve done that, ask if it should try to consolidate other photos automatically. If successful, this should fix all the photos in your project.
If this does not work, I would suggest the following workaround:
- On your source computer (the Mac), move the project file to the shared drive with the photos (if it is not already there)
- Open the project file on the shared drive, and enable developer mode in Tropy’s preferences
- Back in the project select ‘Rebase project’ from the developer menu (just click this once!), wait for a few moments and then close the project.
- Now try to open the project file on the shared drive on the Windows computer and it should find all the images.
At this point, the project is using relative paths to the images, meaning, the project file needs to stay on the shared network drive with the photos. If this is inconvenient or causes performance issues, you can select ‘Rebase project’ again from the menu – this will replace the relative paths with absolute paths again, and you’ll be able to move the project file elsewhere on the target computer.
