Thanks BB for bringing this topic up. I've had Lightroom for about 6 months now. I am relatively comfortable with the develop module, but the library and catalogue features are still mysterious. For 2011 I had asked for photos to be downloaded to a subfolder in 2011. Most of the time it worked, but somehow sometimes the subfolder wasn't checked and they would end up some place else. I tried moving the files and reimporting into Lightroom, but I lost all the adjustments I had made. When 2012 came along things got worse, and now Lightroom seems unable to find a lot pictures listed in the catalog. I can find them in Adobe Bridge, but it sort of ruins the library feature. I was wondering if anybody knew of a clear explanation of moving files around in Lightroom. I saw Kelby's article "Why I never move Lightroom files" but that just confirmed my fears. Any help would be greatly appreciated. Thanks.
