Copy Lightroom Images Directory Structure to New Location

Every Year I plan to create a new LR Catalogue pointing to an empty clone of my Images Directory Structure then fill in images for eventual merging back to the master catalogue.  The following Unix command will create a copy of my directory structure in  /Areca-T2/LR JG Pics    to Desktop/Temporary\ Stuff – just the folders not the files. rsync -a /Volumes/Areca-T2/LR\ JG\ Pics /Users/jeffg/Desktop/Temporary\ Stuff –include \*/ –exclude \* The Folders in Temporary Stuff can then be moved to […]

Lightroom Previews File Size out of Control

LR CC Classic creates a preview of an image for use within the Develop Module and places it in file Previews.lrdata. This file is referenced to prevent the dreaded “Loading” message as you move from one image to another. I had to move my LR Catalogue to an external hard drive because the LR Previews file Previews.lrdata grew to 700Gig for a LR Catalogue of 200k images. Eventually I figured out how to move the Previews.lrdata to a separate external […]

Lightroom – Moving Lightroom Catalogue to a SSD while leaving Previews.lrdata on external disk

My SSD is too small to contain both the LR Catalogue and the previews file because I have 200K images and the Previews.lrdata is 700GB. To improve overall performance I have moved everything in the LR Catlg folder to the SSD except the previews file and placed the Previews on a separate drive which I called Areca-T2. To trick LR into using the Previews.lrdata on Areca-T2 a symbolic line file is used to refer all applications including finder to the […]
