    15GB are for the database file or everything including photos?

    How many images are indexed in your legacy catalog imported from LR? Are they Stored inside the catalog or Referenced? Stored and Referenced catalogs are backed up the same.

    Catalog backups do not include the Originals or Cache folders. They only include the catalog database and Adjustments folder (layer masks).

    I just exported a collection to a new catalog and included the referenced images in the exported catalog. This made the exported catalog a Stored catalog.

    Not a single photo in the catalog.

    The main issue for the bakup is not the data but mostly the empty folder C1 created.

    Can you look in the backup folder and tell us the path of the "empty folder"? See my edited reply above with screenshots.

    The Adjustments folder contains all of the layer masks of all the images. It can grow quite large. Here is a screenshot of my backups folder showing the latest backup from my primary catalog "Masters". That catalog references 66K images.

    Note the Adjustments folder is nearly 3GB. The more images with more layers, the larger Adjustments will grow.

    sure. Hier some examples:

    Have you run a File > Verify Catalog on that catalog? I don't know if that would clean these up. My suspicion is that it will not. I have also observed that Capture One isn't the best at house keeping in some areas.

    I wonder whether this should be considered an "Improvement" or a "Bug". In my opinion Capture One should keep a very tidy folder tree – only create these folders for images with layers, and remove empty folders if all the local adjustment mask (LAM) files inside are deleted.

    The Verify Catalog process includes a checkbox for "Optimize". I imagine that only applies to the SQLite catalog database.

    Sure. It makes no difference

    Or even better, but everything in a single database file - and optimize that. (?)

    On Mac? On Windows I could not see that.

    Is SQLite3 capable of holding that kind of binary layer mask data efficiently?

    Would Capture One be slower if updating a layer mask stored in a database vs a file?

    Could you make a copy of the catalog, find and remove all the "empty" directories in the copy, and do a verify on that copy? Does Verify complain of missing folders? Does a backup go faster? Is the backup tree smaller? This is all just data gathering to provide to Capture One to more fully inform a solution.

    I do not know. They should just make it better :))

    I agree a compressed format also would be better. I provide 1-on-1 assistance to Capture One users over Zoom. Multiple users I have helped have gotten themselves into trouble because they opened and started using one of their backups. Each backup folder looks exactly like a catalog folder. Making it a compressed archive format of some type would prevent that.

    Nicolas,

    Do you know where the empty folder came from?

    Were they something created as part of the Lr catalog conversion?

    Have you considered creating a new catalog and importing the old one to see if it tidies up?

    Or just Export the old catalog to a new catalog. 

    (In both the above cases it may be better to undertake the work in sections it you can work out how to assess any improvement in total size for just a partial copy.)

    On the other hand, empty folders of zero size would seem to be worthless, as you point out, but also should not greatly affect the size of the catalog on disk unless each is allocated a block and the block size set is large. Even then difference would probably not be that great.

    I actually never "dare" to touch to much my catalog. But indeed, it might help. If wou wish we could keep in touch and try next week. I am running out of time.

    Do you work for C1 ?

    Yeah, there might be some trick to clean the catalogue.

    However, empty catalogue have a HUGE effect on filesystem / IO performances. Unfortunately.

    SFA has a great suggestion.

    1. Create a new empty catalog.
    2. File > Import Catalog > Capture One catalog.

    This will safely import the catalog and perhaps not recreate all those empty folders. Once that import is complete you can check if the new catalog has the same empty folders. If it does, provide that feedback here. If it doesn't then try backing up the new catalog. See if it goes faster.

    Nicolas Det – did you try importing your catalog into a new catalog? I'm anxious to see if this cleans up your catalog folders.
