When a customer decides to stop using S-Drive, the files in S-Drive remain stored in their own Amazon account. They will continue to have access but not through the S-Drive user interface. They can bulk download all of them from AWS directly. Also, all the file information (which file is associated to which record and what metadata is stored on the record is still in the customer’s own Salesforce account) can be exported out of Salesforce using a report.
For accessing AWS, customers can use the AWS console, AWS CLI tool or freely available tools such as cyberduck, CloudBerry or CoreFTP. These tools will allow access with no charge to the customer.
If you need assistance, please open a ticket with S-Drive.
