Hi everyone,

I recently had a disk crash and was able to recover most of my fotos from backups, except for a few folders spread over the last 8 months.
I also recovered the catalog including previews folders from another backup which is only one week old.
I use LrC 10.1.1. on Windows 10 rev 20H2 x64 .

When running the recovery script found on Adobe website it seems to work but not fully.

I select all fotos inside a folder in LrC and launch the script, but only some are recovered.
I can view previews in LrC in full size (1:1) by hitting "F", but not all of those I can see in LrC are also recovered by the script.

Any idea why that and how to resolve this would greatly be appreciated!

Thanks

Jens

I do not know this script, but the answer could be simple. What you are looking at in the catalog are not 1:1 previews, but standard-sized previews. A 1:1 preview is only generated when you zoom in to 100% view. So for the images that do not recover there probably is no 1:1 preview.

I found a plugin which does the job, plus - it recovers some metadata and adds them to the restored jpg.
I use plugin version 20201017.61
Jeffrey Friedl's Blog » Jeffrey’s “Extract Cached Image Previews” Lightroom Plugin
But don't make the catalog file name and folder structure too complex, otherwise the plugin messes up and does not find the cache folder anymore.
I finally used this structure, which works for me. Just copy the original catalog to another place and rename.

Catalog file:
==========
D:\Lightroom Catalog\2019-2022\LRv10.lrcat

Helper and Previews folders;
=======================
D:\Lightroom Catalog\2019-2022\LRv10 Previews.lrdata
D:\Lightroom Catalog\2019-2022\LRv10 Helper.lrdata
