If you attempt to upload an asset that exists in Adobe Experience Manager Assets, the duplicate detection feature identifies it as duplicate. Duplicate detection is disabled by default. To enable the feature, do the following steps:

  1. Open the Adobe Experience Manager Web Console Configuration page at https://[server]:[port]/system/console/configMgr.

  2. Edit the configuration for the servlet Day CQ DAM Create Asset.

  3. Select the detect duplicate option, and click/tap Save.

    Select detect duplicate option in the servlet

The detect duplicate feature is now enabled in Experience Manager Assets. When a user attempts to upload an asset that exists in AEM, the system checks for conflict and indicates it. The assets are identified using SHA-1 hash stored at jcr:content/metadata/dam:sha1, which means duplicate assets are detected irrespective of the filenames.
