Thanks for the response, Jon.

If I set the command to include sub folders, the request times out. I noticed a "setTimeout()" API that I'm going to try. However, I think the request is slow because the sever is populating a lot of extraneous data that we don't need for each folder, chiefly "effectivePermissions". I also found an API for setting the command parameters, and I'm wondering if I can use this to filter out response fields on the server side. That said, I have no idea what to populate the setParameters() map with -- the documentation doesn't help here either.

Thanks.
