Find Duplicates

The duplicate search offers various setting options and the dialog is divided into the following sections:

1 Find in: Here you can specify whether you want to search in the entire database or in the current filmstrip. 

2 Duplicate type: In the second step you can specify the type of duplicates. Exact duplicates are photos with identical binary hashes. It should be noted that a search takes longer due to file access and hash calculation. Near duplicates are photos that are visually similar. The degree of similarity can be set from very strict to very loose. Here, very strict represents a high degree of visual similarity. We recommend this mode as the default setting. In the third mode you can find duplicates as image series with capture times that differ only slightly. The time interval of these photos can be adjusted by a slider.

3 Filter: With the filter options you can specify the minimum number of duplicates in a duplicate group and whether duplicates consisting of only one JPG/RAW pair should be ignored.

The results of the duplicate search are saved in collections. The number of duplicates found per group is displayed next to the corresponding folder of the collection.

If you want to delete duplicates permanently from the hard disk, you have different options:

1. Select all photos in the duplicate groups that are to be deleted and then switch to "All photos" view. There, the corresponding photos are still selected and can be deleted.

2. However, we prefer the following variant: use the "Rejected" flag to mark the photos to be deleted. These photos can be displayed later in LrC via the "Rejected" filter and deleted in one go. Or directly via the option "Delete rejected photos".
