Drupal: module for handling public and private files storage

I need to create a web system for handling public file downloads and to create protected directories for single users. Users can see the content of the public folder and can read/write in their directory without, obviously, seeing the content of other users directories. I would like to use Drupal but I have not fou开发者_如何学运维nd a module that permits a similar thing.

Can anyone suggest me links to useful modules?

It sounds like the User Files module does what you're looking for.
