Howdy, @schneida . Welcome to PhotoStructure, and apologies that your first impression wasn’t smooth!
OK: know that PhotoStructure won’t move files already found in your library directory (/ps/library on Docker), so I’d make whatever directory you think is your “best one” be the library directory, and add the other ~300GB folder be an external path in the scanPaths setting (which is set in the “Where else are your photos and videos?” settings section).
If you want to re-launch the windows version with debug logging enabled, I can take a look at what’s going on.
Know that Windows Defender is the only supported antivirus solution: most others cause PhotoStructure to throw timeouts or simply get “stuck” trying to do basic file operations.
Is this on your windows box, or on your UnRAID box?
Know that the spants template in Community Applications has some issues. I’m working with spants to get his template updated, but until then, you can add
https://github.com/mceachen/unraidtemplates to your Docker Containers template repositories and install PhotoStructure via the template there.
UPDATE: I got my template added “officially” to Community Applications!
Also: if this is running on your UnRAID box against a local filesystem, you can skip a bunch of code that may be causing grief by setting the environment variable PS_FORCE_LOCAL_DB_REPLICA to false (read more here)
Good luck!
