7.3 Uploading of files via Extended File Upload/Download Protocol
Extended transfer protocol allows uploading of multiple files and folders in a single transaction and supports pause, resume and cleanup of partially uploaded files for data consistency.
There is no limitation on the size of uploaded file since files are uploaded by the chunks.
The protocol is used by Thru connectors for Microsoft Outlook, iOS and Android applications.
Please see protocol specification in the document Thru Server Extended File Upload Download Protocol Ref x_y.docx available at Thru web site www.thruinc.com.
