This article explains how to use the automatic duplicate detection to sort out duplicate image material or to allow different versions of an image.
When new images are uploaded, the system automatically checks whether an image already exists in the Media Hub. Detection is not based on the file name, file size, or other metadata, but on the actual image content. If at least one image is recognized as a duplicate, a warning is shown in the upload dialog.
In the All duplicates column, each duplicate must be marked with either a green check mark to keep it or a red cross to discard it (Keep all or Discard all shortens the process). Only then can the upload be completed.
On the right, a visual comparison of the suspected duplicates is shown, where it is optionally possible to decide what should happen to the file already in the system. The following options are available:
- Replace file
- Keep both files
- Delete file
This can be done image by image. Selected metadata is compared as well.
💡 Tip: The selection can also be made using the arrow keys and Enter.
Mode when multiple duplicates exist
If several duplicates of an image exist, the number is shown on the left-hand image. It is then possible to switch between the existing files and set one of the three options for each.
Managing duplicates later
To do so, navigate to the notifications (mailbox icon at the top right) > settings icon ⚙️ > Show all duplicates. A comparison follows (as above), starting with the most recently uploaded images.
If individual review is not needed, all duplicates can alternatively be kept or discarded there.
⚠ Note: This action cannot be undone.
Duplicate marking
Duplicates receive a marker at the top left of the preview image. Files with this marker do not appear in external shares. The marking can be removed via the later management (see above) by selecting "keep" for the file.
