Purpose first
Under Document AI → Storage mounts → Create, purpose comes before protocol. Purpose and encryption are fixed after save. Path: /{lang}/document-ai/storage-mounts-overview.
| Purpose | Allowed connection |
|---|---|
| Use as BYOS storage | external SFTP only |
| Use as import source | external SFTP, scanner endpoint, Reverse-SSH, Amazon S3, WebDAV, email (IMAP) |
Azure Blob, Google Drive, OneDrive, Dropbox and Box are locked as Enterprise in the standard UI.
What does not exist
PaperOffice AI has no SMB and no Windows-share connection type. A mapped drive in the file explorer is not a storage mount. Files from a network drive enter import as a ZIP: How do I import data into workspaces?. Larger than 5 GB or 2000 files: SFTP, S3 or WebDAV as an import source.
WebDAV (including Nextcloud, ownCloud or the WebDAV of a NAS) is an import source, not BYOS.
IMAP is the mailbox, not the file server: How do I connect a mailbox?.
The scanner endpoint is an upload point provided by PaperOffice. External devices drop files there. That is an import source.
SFTP reachability: The NAS must be reachable from the PaperOffice datacenter.
