Important information for all platforms

  • The files and file locations given here are defaults. Some of these locations can be customized in the Lightroom \Preferences or Catalog Settings dialog boxes.
  • While troubleshooting, when possible, rename files instead of deleting them.
  • If possible, back up catalogs on a different hard disk or volume from the disk where your catalog is located. For more information on backing up in Lightroom, read Back up a catalog in Lightroom Help and watch the video tutorial Backing up your catalog. (The video was produced for Lightroom 4 but applies to Lightroom 5.)
