[need] free download area script - multi users

Hi,
I'm searching for free & simple download area script for multi-user access.
Let me explain :

want different users to access a place of my site and to have access to files depending of username and password they are using.

For example - creating user
User123 and he has access (view/download) only to file1 , file2 and file3
User321 to got access (view/download) only to file4, file5, file6

 

i can custom code such a solution for you. pm me with your chat contacts so we can talk.

 

thanks for your reply.
I really search for ready and free solution for my case.
