Hi Jon, Please find the responses to your queries below: 1. When the Catalog is backed up by PSE15, is both the Catalog and full sized images backed up, or are the images only thumb nails of the originals?. Upon backing up any catalog, the original images also form the part of backup folder. This ensures that if you are restoring your catalog at any other PC from this backup, the images also get transferred to that PC. 2. In order to restore a backed up Catalog, which files are needed? I have both a .buc file and .tly file. When you select the "Restore From" location in restore dialog, you need to select the .tly file. Find more information at - Back up or restore catalogs in Elements Organizer 2018 3. If I restore the backed up Catalog through the reinstalled PSE15 application, will it reinstall what will essentially be duplicates of all of my images, which are still on my D drive. I really only need the Catalog containing all the tags, etc. Yes, on restoring the catalog, your Drive D data (images) would be again created in the folder which you would select at "Restore Files and Catalog to" section of Restore dialog. Though this data would have all tags organization attached to it. This is designed behavior of restore. When you plan to upgrade to Elements 2019, this duplication would not happen, as then you can use the convert catalog functionality to convert your previous version catalog to PSE 2019 catalog. Conversion migrates the catalogs and its tags organization, reusing the same media from their original location. Let me know in case you've further queries. Thanks.
