Hi,
I have a couple of questions about cache, local copies of originals and smart previews.
- Is it worth to have a local copy of the smart previews when a copy of all originals is already stored locally?
- Are originals stored locally just for backup purposes, or do they have any role in the editing process?
- What's Lr behavior when editing a photo 100%? In particular: does it use the local copy of the original if available or download the original caching it? I assume that Smart previews are not taken into account since they are smaller than the 100% originals. Is this correct?
Thank you for any information you all can provide.
Best
Guido

The smart previews speed up general browsing, and allow you to edit the low res if even you're offline. When you zoom in on a photo or go to edit it, Lightroom looks for an original locally and then in the cloud.
