Enable detection of duplicate assets enable-detection-of-duplicate-assets
If you attempt to upload an asset that exists in ÃÛ¶¹ÊÓƵ 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:
-
Open the Experience Manager Web Console configuration page by accessing
https://[aem_server]:[port]/system/console/configMgr. -
Edit the configuration for the servlet Day CQ DAM Create Asset.
-
Select the detect duplicate option, and click Save.
Figure: Select detect duplicate option in the servlet.
The detect duplicate feature is now enabled in Assets. When a user attempts to upload an asset that exists in Experience Manager, 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.
