Someone just asked this:
Just found out about this app and it looks interesting! One thing I noticed is I have my photos on a read only drive and PhotoStructure wanted it to be writable.
This is easy to set up:
On your settings’ Your PhotoStructure library section, point to a directory on a separate read-write volume (either local disk or remotely-mounted file share).
In the Where else are your photos and videos? section, point to your read-only only volume with your photos. (You can search the documentation for “scan paths” more more details).
I’m not sure what it would need to write to when scanning my images but if it’s possible It would be nice to keep any of the apps data out of my photo data.
PhotoStructure does require some storage to build previews and transcoded videos, but this can be a different volume from your original files.
It will also try to write to sidecars next to all your image variations when you edit assets within PhotoStructure’s UI (so when you rotate an image, for example, it will add or edit a .XMP sidecar with a new
If PhotoStructure can’t write the sidecar, it just logs the error and continues: it should be totally fine with read-only scan path volumes.
