Find Duplicate Photos (Photo DeDupe)

For Mylio Photos+ subscribers, the Photo DeDupe tool helps clean up unwanted duplicate photos from your media library. It starts by scanning your entire Mylio Photos Library and will generate a list of files where it detects two or more copies of the same media.

1. Click the Tools icon in the left sidebar and select Photo DeDupe .
2. Photo DeDupe will list all files with one or more duplicates. Scroll through the list and review the differences between duplicate files. Click here for more information on reviewing duplicate sets.
3. Check the box for the duplicate file(s) you wish to move or delete or use Auto-Mark to have Mylio Photos+ automatically detect the best files and mark the remaining files for removal or deletion.
4. When you’ve finished reviewing the files, click the Delete Marked or Move Marked button.

*TIP: Invoke Photo DeDupe from the Folders or Albums view to apply a QuickFilter automatically that limits the list of duplicates to the selected folder or album.

*TIP: Quickly mark images for removal or deletion using the spacebar keyboard shortcut.

*TIP: If, after marking your photos in Photo DeDupe, you want to take action on all marked images (other than removing or deleting them), you can select all marked images by navigating to the Actions menu > Select > Marked.

How does Photo DeDupe work?

Photo DeDupe uses existing information in your library to quickly identify specific criteria and determine if files are unique. If any of the following conditions are met, it will be marked as a duplicate:

• Exact files that are the same size and resolution
• Exact files that are the same name but in a different folder
• Exact files that match but have different names
• Exact files that match but have different metadata

It is important to note that Photo DeDupe will only detect exact matches. For instance, different sizes, resolutions, or visually similar images, such as a burst of nearly identical shots, will not be marked as duplicates.

*NOTE: Photo DeDupe can be accessed from a computer or tablet with access to all Original-quality files. If your Original-quality files are stored on an external drive, at least one drive that contains the Original-quality files must be connected to the computer or tablet to find and remove duplicates.

Merging Metadata

The Photo DeDupe tool allows you to merge metadata when removing or deleting duplicates. When Delete Marked or Move Marked is clicked, you can Merge moved image metadata into the remaining duplicate file(s). This allows you to retain important information you may have added about your photos, such as IPTC copyright, keywords, title, caption, and more.

When a photo set has conflicting metadata, each metadata field with information will be listed next to each version of the photo. When an image is marked for removal or deletion, all metadata fields present on that file and missing on the remaining image will be shown next to the remaining image, highlighted in yellow, allowing you to preview the merged metadata result.

Some metadata fields can hold a single value, such as a Title, while others can have multiple values, such as keywords.

• If both versions of an image have a title, Photo DeDupe will prioritize the information based on your Photo Prioritization preferences. All fields capable of holding a single value will follow this logic.
• If both versions of an image have different keywords, Mylio Photos+ will combine the keywords from the version being removed or deleted with the keywords on the remaining image. All fields capable of holding multiple values will follow this logic.
