save files on server
<p>I am developing a website for the project on of my course.this is a system with a lot of user and <strong>each user can upload files on server</strong>.  now i have two way for implementation that:</p>

<ol>
<li>create a folder with name files and upload files in that and retrieve from that.</li>
<li>each user have a distinct folder and upload files in that.</li>
</ol>

<p>the implementation of second way is easy but i think create a lot of folder(each user have distinct folder) may decrease the speed when every one try to load them from sever.</p>

<p>whats your opinion?
what way is better? </p>
