How to block duplicate file name upload?

Hi Brains Trust,

 

On onsite AEM DAM I am facing a challenge - users can upload files with the same filenames that already exist in the library. Some filenames are the same, but have either first capital letter or lower case... I want to block such option. Anyone uploading a file with the filename that already exists on the library (case not sensitive) should be notified and not allowed to upload unless file is renamed. 

 

Does such feature exist or is possible on AEM DAM?

 

Thanks

@poveim You can customize AEM's Asset Upload feature. Here’s how:

1. Event Listener/Workflow: Set up an event listener (or workflow) that triggers on asset upload. This listener will check the filename against the existing assets in the DAM.
2. Custom Validation Logic:
- Implement a service that performs a case-insensitive search in the DAM repository to check if any file with the same name (ignoring case differences) already exists.

3. Upload Restriction: If the query returns a match, block the upload process by throwing an error in the validation logic, notifying the user that a file with the same name already exists.

4. User Notification: Show a user-friendly message to the uploader to rename the file if there’s a conflict. You can leverage AEM's Granite UI framework for this, or a custom frontend dialog if needed.

    Thank you for the reply, Diksha!

     

    It seems creating this workflow on my own is beyond my knowledge of the AEM DAM at the moment. I'll raise a ticket for this workflow to be created. 

     

    Many thanks!

      Hi ,

      OOTB AEM Dam doesn't have this feature. However , if you still need this you can customize this as below :

       

      Develop a custom OSGi bundle implementing AssetUploadNameValidator interface. Override the validate method to check filenames with existing name (case-insensitive) logic. Register the bundle as an OSGi service and configure it in AEM's OSGi settings.

        Hi Digarg,

        Thanks for the another option on this matter. I will pass this to the devs. 

        Meanwhile I will be downloading entire database CSV, marking duplicate filenames through conditional formatting and fixing them manually.

          @poveim 

          There is one feature which checks the duplicate Asset Detection by checking SHA 1 checksum value.

          Its the popup that appears when user upload the same asset even if the filename is different. 

           

          Check this document 
          https://experienceleague.adobe.com/en/docs/experience-manager-cloud-service/content/assets/admin/detect-duplicate-assets#:~:text=Navigate%20to%20Tools%20%3E%20Assets%20%3E%20Assets,if%20the%20filenames%20are%20different.

            Thanks @khamat_bn ,

             

            I forgot to mention I am on 6.5 onsite version which advises this: https://experienceleague.adobe.com/en/docs/experience-manager-65/content/assets/managing/duplicate-detection

            It does detect duplicates via pixel recognition but if there are two different images with the same filename it lets it slip.
