Hello,
Do we need to upload our attachments from Amazon S3 to your GroupDocs server for the document to be previewed?
Hello,
Thank you for you request.
You don't have to download your attachments from Amazon S3 to our GroupDocs server. We have a feature of synchronization with Amazon S3. Please check these
documentations for how to integrate GroupDocs with Amazon S3.
If you will have more questions please feel free to contact us.
