Trigger TinyMce File uload

I am using TinYMce WYSIWYG editor, It is working fine. I am using OpenSource product without MCFileManager, instead files/images are uploaded via TinyBrowser which is included. Now I need to trigger this pop-up window where I can browse files to upload from element. Is there any way to do that via upload files?

P.S Maybe there is a way to get t开发者_如何转开发hat MCFileManager for free or some kind of license?

You can find the available licences and prices here, you won't get it for free (at least not leagaly).

I never used TinyBrowser, but i am sure you could write your own Tinymce plugin and include your own button to trigger the TinyBrowser.
