Some standard previews were not created

I tried to create standard previews for all photos. With 74,000 photos, this takes half a day. At the end, a window appeared with the message: "Some standard previews were not created. Photos not found (126). Photos could not be created (43).“

 

And now to my question.

 

In the bottom line, I have the choice between ”Save as...“, ”Show in library“ and ‘OK’. 

 

If I choose ”Save as", will only 126+43 be saved, or 74,000-(126+43)?

If I select “Show in library,” will only 126+43 be displayed, or 74000-(126+43)? Can I still go to “Save as...” after selecting “Show in library”?

What happens if I go directly to “OK”?

 

Correct answer JohanElzenga

@JohanElzenga Before I deleted Lightroom Catalog - v13-5 previews.lrdata, it was located in the Lightroom folder. Where is this folder now? I expected this folder to reappear in the Lightroom folder after creating the standard previews.


Lightroom should rebuild it in the catalog folder. If it's not in what you think is the catalog folder, then most likely you are looking at an old catalog folder that is not in use, not the current catalog folder.

"Save as" just saves this message as a text file.

@JohanElzenga Thank you. You are right. 

 

With “safe as,” you get a text file with all the file names for which NO standard preview could be created.

 

“Show in library” is a kind of smart collection containing only the affected previews that cannot display a standard preview. This collection is also listed on the left under ‘Catalog’ after “Previous import” under “Photos for which no preview could be created.”

 

Strangely enough, the number of “All photos” has increased from 74,000 to 75,000.
