File association for editing (doc -> Word, txt -> Notepad,..)

Is there any way to determine different editing-programs for different file extensions!? It would be a great feature to edit doc-Files on the server with Word, but html-Files with a HTML-Editor..

Any way to do this?

No. The edit feature is meant for web-programmers to edit plain text files, and thus only uses the one editor as defined in the settings. You will have to manually download, edit and upload Word files.
