I would change the Output File parameter pointing to the target location as the way it is explained in this KB article "[Changing the output location for CSV exporter](https://community.denodo.com/kb/view/document/Changing%20the%20output%20location%20for%20CSV%20exporter?category=Scheduler)" as long as the path is open to access. For the network location, I would use the following format,
To use the secured location that requires username and password, I would create my own JAVA based Custom Handler using [Denodo4E](https://community.denodo.com/docs/html/browse/7.0/denodo4e/index#denodo4e-user-guide) extension available in the directory <DENODO_HOME>/tools/denodo4e, and deploy the developed Custom Handler in the Scheduler Server.
You could find samples for Scheduler Custom Handler in the directory, <DENODO_HOME>\samples\scheduler\handler-api.
For more information on creating a Custom Handler, have a look at [Handlers](https://community.denodo.com/docs/html/browse/7.0/scheduler/administration/developer_api/extensions_plugins/handlers#handlers) section of the Scheduler Administration Guide.
Hope this helps!
