Hi

Generally speaking, you'd better develop your bulk upload tool. This is relatively easy using the API REST protocol.

We did that to develop a migration tool to transfer documents from an ancient GED system toward Nuxeo, using python.

If you mail me your context, I might send you the python library we develop to obtain this.

Have you tried the following? https://doc.nuxeo.com/display/NXDOC/How+to+Upload+a+File+in+Nuxeo+Platform+Using+REST+API+Batch+Processing+Endpoint

Hope this helps.
