Title: Pictures folder Lightroom file question
Post by: billh on January 25, 2010, 11:55:27 am

In my Pictures folder (the one with the camera Icon, Users/billhollinger/Pictures/Lightroom) there is a Lightroom folder, and in it is a file named: Lightroom 2 Catalog Previews.Irdata Dec 31, 2009 (probably the last time I used Lightroom) 34.44 GB. I would love to free up this much room on my HD. If I copy this file to an outboard RAID drive, or another internal HG and trash it from the main HD, will Lightroom still work? What do I lose?

Thanks!

Bill

The Lightroom 2 Catalog Previews.lrdata file is usually stored alongside with the Lightroom 2 Catalog.lrcat. You'll need to move both the Lightroom 2 Catalog Previews.lrdata and the Lightroom 2 Catalog.lrcat files to another drive. Deleting the Lightroom 2 Catalog Previews.lrdata file (or moving it to another drive) will accomplish nothing but Lightroom will recreate it and redo the rendering which will take time.
