Just in case. I found this to work:
get_dir_file_info('./path/to/dir',false,true);
once I added the last two bool params it worked for me.
Looking at the func signature shows this:
function get_dir_file_info($source_dir, $include_path = FALSE, $_recursion = FALSE);
looks like recursion is off by default.
Not sure if this is the latest version though so check the helper source and see if its the same as what I found.
