rob_w Posted July 31, 2010 Share #1 Posted July 31, 2010 Advertisement (gone after registration) I upgraded to LR 3 last week and noticed that the size of the Catalog Previews file increased from about 200Mb to approx. 11Gb. Since this is an enormous increase I am a little worried that all is well. Has anyone else noticed or experienced a similar leap in Preview file size?

elgenper Posted July 31, 2010 Share #2 Posted July 31, 2010 Gee, you´re right! Haven´t noticed before, but mine has increased from 438 MB to 24 GB! I think there is an explanation, however. My Catalog Settings pane specifies that previews should be discarded after 30 days (same in both versions), and it seems that the new version has run through the entire library while converting (just 3 days ago or so in my case), so every single image now has a preview (since it was accessed less than 30 days ago). Selecting "show package contents" for each previews file shows that most subfolders are empty in the old one, while all are occupied in the new, which is exactly what would happen in such a case. If my surmise is correct, the size will start to go down again after those 30 days, and things will return to normal. If one has disk space problems, one could always specify a shorter time.
