Hi, list.
I want to implement this feature in a site (some files only available to authenticated users), already saw how to protect a page (node_privacy_byrole module), and how to upload files (attachment module). I already saw a discussion of the exact same problem (in http://drupal.org/node/23882), but my concern is that uploaded files are visible to anyone who knows the exact URL of the uploaded files (at least when I implemented it). Anyone can give me a direction to follow, even if a have to learn a bit of php?
