How to..? Files management

Dear Drupal experts,
I'm thinking of using Drupal for creating a scientific calculations web portal. Is it possible and how to do the following things with Drupal:

1. I need to automatically create a user directory for every new user registering to the protal.
2. I need to automatically copy some files to the newly created directory (same files for all users).
3. I need users to have ability to manage files in their own directoris: upload and delete files, make subdirectories etc.

I have some knowledge of PHP and SQL.
The portal will be hosted on a Linux machine with Apache, PHP and MySQL.

I'm humbly asking for your support.
