Rebuild missing previews

[Roni Ziv]

Recently I tried to rebuild all standard previews. After the process has reached about 90% the disk that stores my catalog and previews got filled up and the preview generation process stopped.

I've moved the catalog to a new and bigger drive and would like to resume the preview generation process from where it left off.

As I have about 150k images rebuilding the entire catalog would consume much time.

Is there a way to have LR rebuild only the missing preview files?

Thanks, Roni

I am not sure if 'Build Standard-size Previews' builds them for all selected photos, or just for those selected photos that need their preview to be (re)built. You do not really have to do this, however. Lightroom will automatically rebuild previews if and when needed.

Just run "Build standard previews" as you did already for all photos.
Lightroom will skip those that already have previews built, so it will not take more time that is needed.
