Hi Bill,
Good day to you.
Currently we have not provided the folder upload support for file explorer component , since the folder upload support only available in the recent version of chrome and fire fox browsers and not completely supported by other browsers. Due to this inconsistency, we have not provided this support yet. Once the major browsers implemented this HTML5 directory support, we will consider this feature from our end and implement in the file explorer component.
Regards,
Keerthana.
