create file at client side

[Guest]

How can create a file at client-side?
I need verify (find, create and delete) a temp file at client side.
How search a path(file) in differents OS (mac, windows)

You can't really do that unless you convince the user to run an ActiveX
control in the browser.

It would constitute a serious security issue if you could do it directly
from the browser.
