WMS File Attachments

Hello,

I would like to clarify a few questions regarding the process of attaching documents in WMS, as well as the Attachment Upload API. The customer needs to attach documents for each outbound order.

1. Where should the document be storaged, so that it can be referenced by the API?
2. We understand there is a 10MB limit per file, but is there a total attachment limit?
3. Will these files be purged after a certain period?
4. Is it possible to trigger the printing of these attachments via API or through the WMS screen? Or only in the UI-Attachments.

Thanks
