I am hoping someone can help me with my problem. I was using Lightroom 5 that was installed on a desktop with one large C drive. In other words, the software, catalog and all files were on the same drive. Recently I have acquired a new computer that has a small SSD C drive and a large storage drive D, and I have moved all my pictures to the D drive. Now when I install Lightroom on my new computer C drive and use the existing catalog copied from the old computer, for the most part, the software cannot find my pictures. I am assuming it is due to the fact that the path of the location of the pictures has changed from C to D. I tried using library > Find all missing photos, but that didn't help. Is there a way for me to install Lightroom 5 on the new computer and use the catalog that I copied from the old one? Otherwise, my option seems to be to rebuild the catalog, which I think means that I will lose all the tags.
Thanks in advance for your help.
You need to tell Lightroom that the top level folder that contains your photos on the C: drive is now the top level folder that contains your photos on your D: drive.
