>From the PHP error message, your memory limit is still too low.  A more 
useful question might be, "Why does it require so much memory to download 
a folder and how can the memory footprint be reduced?"  Note - I can 
trigger this error on my system also with a mailbox that is approximately 
1/3 my php memory limit.
