Files remain in AWS storage even after deletion from Salesforce org

Since the files remain in AWS storage, customers can implement a custom cleanup process if required.

A common approach is:

• Build a process to identify files that are no longer referenced in Salesforce
• Use the stored external file reference (for example, the S3 key)
• Perform a deletion operation directly in AWS (S3) for those unreferenced files

This can be achieved through custom flow logic such as -

• Create a Record-Triggered Flow on the ContentDocument object
• Trigger the flow when a file is deleted
• Retrieve the associated ContentVersion record
• Extract the ExternalDocumentInfo2 field from the ContentVersion record (which contains the S3 object key)
• Use this key to invoke a DELETE callout to AWS (via Named Credentials or API integration) to remove the file from S3

This approach ensures that files are cleaned up from AWS in alignment with deletions in Salesforce.
