Keep a Lightroom catalog together with photographs on an external drive.So what are the options for using a Lightroom catalog on multiple computers? Let’s take a look at some options:

True multi-user applications require a server and client infrastructure, which can be too complex for most photographers to set up and use. While some people have been requesting a “multi-user” edition of Lightroom, Adobe currently has no plans to make such Lightroom version due to potential complexities of such software. In short, Lightroom is a “single-user” application with no support for multi-user access. On top of that, Adobe strictly forbids placing catalogs on network volumes, because it can result in all kinds of Lightroom database corruption issues (placing photographs on a network share is supported). Hence, simultaneously accessing a single catalog with multiple machines is not supported and will not work. Unfortunately, the database system that Lightroom runs on (SQLite) limits the catalog to be used on a single computer, on a locally attached drive.

If you have more than one computer at your home to work on your photos with Lightroom, you might be wondering if there is a way to share your Lightroom catalog, so that you can work on the same images with the same catalog on multiple computers at once.
