As some of you may have noticed, there is no way to rename a Lightroom catalog from within the program. Instead, locate your catalog (see yesterday’s post) and then quit Lightroom. There are TWO files that you need to rename. They are:

(your catalog name).lrcat

(your catalog name) Previews.lrdata

Make sure that you leave the space between the catalog name and the word Previews on the .lrdata file.

    Thanks… this is coming at a good time when I need to do this. Also, what is your recommendation on multiple catalogs vs. one? If multiple, are they organized by year, event?

      I have two videos that might help (below) and another one that will be out in a few weeks on “Merging Catalogs Together in LR”:

      November 11, 2010 — Single or Multiple Catalogs in LR3?
      In this episode of The Complete Picture Julieanne answers one of the most commonly asked questions,”should you use a single catalog for all of your photographs or should you use multiple catalogs?” As a general rule, she recommends that you use as few as possible, but discusses when using multiple could be beneficial. 2010-11-10

    Hi Julieanne.

    I have come across your posts on numerous occasions for my Lightroom questions. I was hoping you could help.

    I need to re-organize my LR catalog and replace 2 internal HDs (in which my photos sit) in my Mac Pro with 2 larger drives. I currently have one huge catalog of about 55,000 photos and growing daily. This is too big. I would like to take some of the older photos, move them to a bigger internal HD and have them stored in a new catalog that houses older files and name this old catalog appropriately. I would then like to takes the photos that are remaining in the current catalog and either export them to a new catalog, or just rename the existing catalog (not sure which is best/easiest) and then move these files to the other bigger internal HD. This will be my new working Catalog.

    Not sure whether to use the export/import to catalog commands to achieve this or whether to just copy the files to each of the two new catalogs. Also, I don’t save metadate to file, so there are no xmp sidecar files and I obviously amongst other issues, don’t want to lose my develop settings.

    I also have develop and export presets, etc, as well as software like Nik and Onone linked up to LR, however, this is likely done at the program level and not at the catalog level.

    Finally, where do you suggest storing the lrcat and library files (I have 4 HDs in the mac pro). Would you keep these files in the main operating system drive and just use the other drives to house the photos and that way the photos are separate from the lrcat and library files?


    Thanks in advance,

    I imported my Lightroom 2 Catalog into Lightroom 4 and everything seems to work fine except when I do an “edit in”. When I save the file it does not appear in the lightroom preview even though it increases the image count in the keyword list . When I close down and restart Lightroom the edited image shows. What do I need to do to fix this?
