Lightroom CC 1.3 and Lightroom Classic 7.3 were released on April 3, 2018, and introduced a change in file format for Lightroom Presets.

Prior to this release, Lightroom Develop Presets had the .lrtemplate file extension, and were stored in a Lightroom-specific location.

As of Lightroom CC 1.3 and Lightroom Classic 7.3, Lightroom Develop Presets have the .xmp extension, and are compatible with the Adobe Camera Raw importer in Adobe Photoshop.

Presets in Lightroom Classic 7.3 and later are stored in the same location as Adobe Camera Raw, so installing the Prolost Presets for Lightroom Classic now means that they’re installed for Photoshop as well.

If you have .lrtemplate presets installed and then update to Lightroom Classic, your presets will automatically be converted to .xmp and relocated to the new folder. The .lrtemplate presets are left in place for compatibility with older versions.

Presets in Lightroom CC 1.3 and later are stored within the Library (.lrlibrary) file, and should not be administered from outside the Lightroom CC app.
