I need button for file upolad?

Hello, i saw in FCKeditor that there is button for link, image and flash upload. But there is no button just for file upload with own icon.

Im ask for this button for usability reason. Because the pepole which will use my editor are not advanced users and they will look for button and icon for file upolad like pdf, doc, ppt, rar.

How can i add a new button for file upload, the fuction should be with two tabs - upolad file -> choise name -> insert link to file into page content.

Thanks to everybody for answers.
