Have you tried selecting everything, then exporting the whole catalog to a new catalog? How large are the master files? What kind of files are they ... raw, JPEG, TIFF, PSD? Are the masters on the same volume as the catalog folder? How much free space is on the volume? How big is the Camera Raw cache? (LR Prefernces- file handling tab)
My "in progress" catalog has 78,000+ photos in it now. The .LRCAT file is about 1.5G in size. It's on the internal drive of my MacBook Pro 13" (2.4Ghz, 8G RAM, running Mac OS X "Lion", with about 130G free on the startup volume and a 10G camera raw cache). Takes about minute to load. -- Godfrey godfreydigiorgi.posterous.com -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
