Just copy 'FileManager' folder to a folder on your webserver.

• Single self contained package
• Ajax based so it is fast, but doesn't break the back button
• Allows drag and drop file uploads if the folder is writable by the webserver (chmod 777 your/folder)
• Suits my aesthetics. More like Dropbox, and less like Windows Explorer
• Works with Unicode file names
• The interface is usable from an iPad
• XSRF protection, and an optional password.
• Files stored in a 'public' folder
• Enable usage statistics for bandwidth usage and storage usage

If you allow uploads on the public web, it is only a matter of time before your server is hosting and serving very illegal content. Any of the following options will prevent this:

• Don't make the folder writable by the webserver chmod 775
• Set $allow_upload = false
• Use a password $PASSWORD = 'some password'
• Use a .htaccess file with Apache, or auth_basic for nginx
• Only use this on a private network

• Limit uploads based on storage remaining
• Limit Bandwidth access to files (even hotlinked) if bandwidth is exceeded
• Files stored in a 'public' folder instead of the root
