What are XMP Sidecar Files in Lightroom 3?

By Pye Jirsa on May 12th 2011

(The Lightroom video tutorial in this post is just under the introductory text below. The working files for this video can be found in any of the articles within the Creating Catalogs and Importing Chapter)

You may have previously heard the term XMP or Sidecar files, but you may not know how handy dandy these little files actually are. The term XMP and Sidecar files are actually synonymous and are in fact just short for the full term XMP Sidecar Files.

XMP files are used to store develop settings for RAW files. With an XMP Sidecar File, RAW files can be passed between software applications, or even two different computers while retaining all the develop settings from Lightroom.

In this video, we will discuss everything about XMP sidecar files in Lightroom, as well as show you exactly how they work.

    If you turn on the setting to automatically write changes to the XMP file in the catalog settings will the LR adjustments also still be in the Lightroom catalog?
