Duplicate Detection

Duplicate files are detected and automatically skipped when indexing, so they appear only once in search results and albums. Their SHA1 checksums and sizes are used for comparison.

Browsing, analyzing and deleting duplicates via Web UI is planned for a future release.

File Import

When importing, files are first copied or moved from a temporary folder to the originals folder. In the process, duplicates are automatically skipped. "Move" also deletes them in the source directory as if they were successfully moved.

In addition to exact duplicates, there may be similar pictures and related sidecar files (with the same filename) in your library, for example:

  • raw + jpg + xmp
  • jpg + json
  • original + edited version
  • original + compressed version
  • live and timelapse photos

Depending on your library settings, such files may be automatically grouped into stacks:
