    Split Large Catalog into Several Smaller Catalogs

    I have a LR CC catalog with over 126K images, can I break it into multiple smaller catalogs to speed up loading & editing? If so, how would I go about doing it? Thank you.

    Very slow backup on 3TB local drive

    Hi, I'm new to Lightroom Classic. Up to a couple of days ago catalog backups were almost instantaneous (the catalog size is only 140Mb). Now, however, I have tried to close LR and said yes to the backup now question. An error message appeared to say that it could not back up to the location...

    Catalogs Lightroom was unable to back up the catalog named “Lightroom Catalog-v12”

    Title says most of it. Recent upgrade to LR Classic 12.0.1., on Macos Monterey 12.6.1 I back up the catalog on every exit, to a folder on my (Synology) NAS. This has worked reliably under previous versions of LrC. Now, I reliably get this error message towards the end of the backup process...

    Struggling with large 169GB Mobile Downloads.lrdata file after moving from CC to classic

    I had previously used Lightroom CC (and still have an active subscription for it). I moved over to using Lightroom Classic a few months back. Everything worked out (albeit, a mess. I have a large 250gb unstructured folder of jpeg/raws on my external that I can't figure out what to do with)...

    Migrating Multiple Catalogs from Classic

    Hi, I’m in the process of moving from classic to Lightroom cloudy. I’m short on storage space and wondered if there’s anything wrong with exporting each of my collections in LRC as catalogs and importing them one at a time. Ie let one catalog import and sync to the cloud - then the next etc...

    Moved photos to external drive; now LR shows no photos

    I knew this would be fraught with risk, but I really needed to move my photos (several thousand files) to an external drive. After doing that, I can see the correct volume in LR, as well as the parent folder and the folder that contains the photos. However, the latter shows no photos now...

    Catalogs Upgrading PC Platform—Sanity Check Please – Part Two

    Hi, It seems that time has passed by quickly since I wrote my previous post in January 2022 about rebuilding my PC and rejigging the discs. Well that is now all done; in the end I opted for a 1 TB SSD which is now happily running Windows 10 and all the various programs including a move from...

    Best way to access LRC catalog and masters from more than one machine

    First of all, I'm sorry. I know the catalog topic in this forum is a more-than-dead horse but I don't seem able to find a single answer to this issue. What is the BEST(as in MOST EFFICIENT and least-prone-to-error) way to access a LR catalog for editing from more than one machine? Local or...

    Catalogs Downloading catalogue from cloud backup after disk reboot

    11.4 catalog issue

    I updated my version of LR to 11.4 and the first thing that happened was a conversion of my catalog to v11. I soon discovered that this catalog was missing the most recent entries . Nothing after 2020 was there. Somehow it was based on an earlier catalog than the one I have been using. I...

    Collections Unlinked with Catalog

    Please help! I am having serious problem with Lightroom Classic. I shot myself in my foot by changing my folder and file structure outside of Lightroom. I relocated my photos to their locations by syncing to the new locations. I can see and work on all photos at the new location. However...

    Reconciling Lightroom Classic to Lightroom (cloud) - Part 2

    I'm continuing to work on reconciling my LrC catalog to my Lr catalog and with the help I received in my last post, I've gotten remarkably close. I've now got the two 42K image catalogs reconciled to within 200 images of each other. As I've gotten closer, I've uncovered some new things I don't...

    Should I create a separate catalog for my scanned negatives?

    I've got about 45K pictures in my current catalog. I had been scanning my old 35mm negatives and slides 4 at a time using my Epson V600 Photo scanner, but it is mind-numbingly laborious. I've decided to have a service do it for me just to get it done so I can finally pitch all of my old photos...

    Using LRC with NvME drive

    Hi I've just spent my pension on a new PC with a 2TB NvME drive for LR catalog and my photos. I copied the catalog and photos to the n=NvMNE drive & double-clicked on the catalog on the NvME drive but LR doesn't "see" the same NvNE drive where my photos are stored. How do I get LR to see my...
