    Lightroom Library.lrlibrary and Mobile Downloads.lrdata File sizes

    jeffreyp91318676 Level 1

      I've searched the online docs and forums for this issue and I find similar discussions/replies, but not exactly my issue.  I use LR Classic CC Lightroom CC.

       

      I have about 43GB of files in the CC cloud, but this Lightrooom Library.lrlibrary file is 90 + GB on my Macbook's HD.  I looked at the settings for the photo cache and it was set to 25% with no local storage.  I reduced that to 10%.  Shouldn't this .lrlibrary file shrink down?  Why is the local file twice the size of my cloud storage? Is there anyway to reduce this fie size?

       

      I also have a file called mobile Downloads.lrdata that is 30 + GB.  I have some folders in Classic that appear to be mobile downloads, but not anywhere near 30 + GB.  Why is this file so big?  Is there anyway to reduce this file size?

       

      Sorry if this has been answered before, but I cannot find any answers suitable to my situation.

       

      Any thoughts you may have are greatly appreciated.

          The default cache in LRCC 1.3 is managed intelligently (as long as store a copy locally is not enabled) but it can sometimes take a while for files to drop out, after import or migration.

           

          But you can clear the originals manually once you are happy that everything is backed up in the cloud.

          Go to your Pictures folder and right-click (control-click) on Lightroom Library.lrlibrary and choose “Show Package Contents”

           

          You should find a folder with a long string of letters & numbers. Navigate to the folder with originals and you should see files in dated sub-folders.

           

          It is safe to trash everything in Originals.

            So this is excellent and worked as advertised.  My very crowded hard drive thanks you.

             

            Do you know if I can do the same thing to the mobile Downloads.lrdata file?

             

            If you know, will the .lrlibrary file perform more intelligently now?

             

            Thanks very much for the excellent answer!
