You created a file on web server?
or some where?

Hi evanjht,
I thank you for answering, but I want to know whether my problem have to orient oneself !
If true, I want to create a file on web server.
Thanks!

I still not quite sure about your problem.
for file storing, you must specific a path for your file (either do this by your self or by default path setting)

I think the focus must on determine the storing path.
if you create the file on local machine, you can speicify the path directly. On web server, you must get project's path on server first..
