Despite of the existing duplicate detection when uploading assets, duplicates often accumulate in the DAM system over time, which not only wastes storage space, but more importantly can also lead to inconsistent metadata, as not all asset are tagged correctly, or because you assume that an asset can no longer be downloaded when you deactivate one.
Based on their checksum, this plugin checks all current asset versions in the system for duplicates and displays them in the UI. A list of all affected assets can also be downloaded as a CSV file.
In the detail view you can decide which asset to keep and which nodes it should remain assigned to. Furthermore, you can also decide (taking into account the possibly different asset types) which information fields from all of the duplicates should be synced to the chosen asset.
