Create New Text File Icon Finder Window

The syntax to make Finder create a new blank RTF document is:

tell application "Finder" to make new file at (its front Finder window) with properties {name:"foo.rtf"}

A .rtfd is a package folder and Finder cannot make one of those.

The following AppleScript will write out a "Untitled.txt" text file and then using the path to that text file, make an RTF file of it that contains minimal RTF syntax so you can double-click on it and open in TextEdit.

use scripting additions

tell application "Finder"
	try
		set x to make new file at (its front Finder window)
		set FWpath to POSIX path of (target of its front window as text)
		do shell script "/usr/bin/textutil -convert rtf " & (FWpath & name of x) as text
	end try
end tell

You can use the with property clause and assign an arbitrary text filename and that will be made into an RTF file too.

If it is a text file, double-click on it and the default application (TextEdit) will open it. If it is an RTF file, then it will have no RTF instructions inside of it and although the operating system may give it an RTF icon, applications like TextEdit and Pages that expect those RTF instructions will refuse to open it, when LibreOffice Writer can.

You are welcome.
