Hi to you all,


* For getting the listing of a directory, I do not feel any difference
in speed in between ftp.nlst ("/") and ftp.retrlines("LIST",
list.append). My connexion is extremly slow. This may explain why.
Also using nlst, I do not know which is a directory or a file. I have
trouble then to walk the directory structure in search for my file.

* I do not want to use the os.path.walk since this program send
several thread to each of the directory. I feel this recursive walk is
simple enough not to use os.path.thread.

* For names wich includes spaces caracters, I think that the advices
that you gave me will do the trick. I was just hoping for something
more general. But since I will work on a the same couple of servers it
will do the trick.

Thanks for yours quick responses.

Sebastien.
