A great way to keep your Kontainer lean is by using the image Duplicate Manager and Detector. The Premium and Enterprise plans include this feature. To activate get in touch with Customer Success.
There are two separate mechanisms at play, and it's worth knowing the difference:
- Uploading a file with the same name triggers an upload-time prompt (Overwrite / Keep both / Skip), which is really a versioning feature.
- The Duplicate Detector is a separate tool that scans file content — not file names — to find true duplicates anywhere in your Kontainer.
Uploading files with the same name
If you upload a file with the same file name as an existing file in the same folder, a warning box appears with options to:
- Overwrite
- Keep both
- Skip
This is a versioning feature: it only triggers when the file name matches a file already in that exact folder. It does not compare file content, and it does not run if you're uploading to a different folder.

Duplicate Manager and Detector
Premium+ Feature
The Duplicate Detector is a separate feature from the same-name upload prompt above. Instead of comparing file names, it generates a content hash (SHA256) for every file and flags files as duplicates whenever their content is identical — regardless of file name, regardless of which folder they're in, and regardless of file type. This means images, videos, PDFs, and documents are all covered, not just images.
There are four key ways to use the duplicate detection tool:
- Duplicate indicator
- Global scan for duplicates
- Track the location of duplicates
- Scan specific image duplicates
Here is a very quick and straightforward guide.
Duplicate indicator
When the tool is active in your Kontainer, any file with a content-identical duplicate elsewhere will be marked with the duplicate icon at the bottom left of the thumbnail — this applies to images as well as videos, PDFs, and documents.

Global scan for duplicates
To scan your entire Kontainer for all duplicates, click the button at the top of your window next to the search bar. You can do this from any folder, and it will scan your entire Kontainer — matching files by content across all folders and file types, not by file name.

Track the location and manage duplicates
When using the global scan, you can find the location of each file by hovering your cursor over it. From the results, you can, of course, delete the duplicates and keep the one that is placed in the desired folder.

Scan a specific image for duplicates
If a file has the duplicate icon, you can find its duplicates by right-clicking it and selecting the option Find Duplicates.

That's it, really. Let us know if you have any questions.
