To clean your duplicates, please navigate to the channel “Admin” or “Administration” . In this channel, there should be a filter called “Duplicates (Hash)”. If there is no such filter, you could either try to add this filter by yourself or contact support@picturepark.com.

If you expand this filter, you should be able see the sha1hash codes of all files stored in your Picturepark. The sha1hash code is a cryptographic function and can be referred as a signature that gets assigned to a file. If there are multiple files with the same sha1hash code, these are duplicates and can get cleaned.

If a Sha1Hash code is used multiple times or not can be identified when hovering over a code in the filter. The Sha1Hash code which is used by the most files is displayed on top of this filter.
If the first sha1Hash code is only used once, there are no duplicates in your system and therefore no data cleaning is necessary.
