Allow folder selection in "File Browser"

Issue Summary

We would like to use filefield_sources and imce to allow users to select a folder on our Drupal server and save that folder path and filename in a File field. Using the "File browser" feature allows us to browse folders on the Drupal server, but only allows the selection of regular files. We would like to allow selection of folders as well.

What would be the best way to achieve this feature?

Thanks,
