Capture One can determine if a source image or a movie file is a duplicate of another one that is already in the Session. This feature is particularly useful when importing from memory cards that haven’t been erased or formatted yet. 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 Session database are removed from the importer’s browser and excluded from the import.
If you bypass the import dialog and use the drag-and-drop method to import files directly into a Session sub-folder, then Capture One can’t recognize potential duplicates. Capture One also can’t identify duplicate images once file extensions have been modified. In case the option to Pack RAW files as EIP on import is altered frequently (from the application preferences), there is the possibility that images may be duplicated if reimported at a later date. When importing an adjusted image with the settings file (e.g., when copying images from a folder that have already been worked on in Capture One) into a Session and the Include Existing Adjustments option is enabled in the importer, the image is considered as a duplicate.
- Open the import dialog window (in the main menu, File -> Import Images).
- In the Import From panel, select Exclude Duplicates. This option can be left enabled for the future use.
