Capture One can determine if a source image or a movie file is a duplicate of another already referenced or managed by the current Catalog. You can specify the importer to ignore image duplicates when importing from folders that are already on your computer or an external drive (for example, when importing your existing image library into a Catalog or when importing images from a memory card to your local computer or an external drive). This feature is particularly useful when importing from memory cards that haven’t been erased or formatted between use. Previously imported images remaining on the card can now be excluded from the import process, thereby preventing unnecessary duplication.
After enabling the feature in the importer dialog window, images are individually scanned in the importer’s browser prior to import. Images that match key metadata in the Catalog’s database are removed from the importer’s browser and excluded from the import. When importing a previously adjusted image with the settings file (e.g., when referencing images a second time from a folder on your computer) and the Include Existing Adjustments option is enabled in the importer, the image is considered a duplicate.
NOTE: The import dialog can’t identify duplicate images when files have been saved in a different format.
1. Open the Import dialog window (in the main menu, File -> Import Images).
2. In the Import From panel, select Exclude Duplicates. This option can be left enabled for future use.
