WP7 Accessing phone files and folders

Question

How to access the files and folders from the phones memory not application memory(i.e isolated storage) ?

Answer 1

It is not possible. Every app has its own directory and permissions to operate inside it. There is no chance to get to files outside that directory.

You can use launchers and choosers to get some data from other places (like contact list or photos) but you cannot get to that files directly.
