How to grant PHP write access outside outside the httpdocs?

[DeepInside]

Hi,

how is it possible, to grant php write access to any folder on my windows system? For example: I want to let php create files on C:\Users\SomeUser\Downloads\

How can i do that?

I manually set the permissions of my IUSR_xxx to this folder and put the path in the php "open_basedir", but it doesn't work.

Any help?

Thank you!
