How do you add file extensions to a bunch of files at once?

[Chakravartin]

Oh!

And this script will rename every item in a folder.

set the_folder to (choose folder)



tell application 
Finder
	set the_files to (every item of the_folder)

	repeat with i from 1 to (count of the_files)

		set the_name to (name of (item i of the_files))

		if the_name does not end with 
.txt
 then

			set name of (item i of the_files) to the_name & 
.txt
		end if

	end repeat

	

end tell
