[InDesign] How can I extract out the folder name from the file path?

My objective is to extract the folder name from the file path of my linked images in InDesign document. My script is as follows:-

tell application "Adobe InDesign CS2"
	activate
	tell document 1
		set theLink to every link
		repeat with i from 1 to count of theLink
			set oriDelims to text item delimiters of AppleScript --puts the current delimiters into a variable
			set theImagePath to file path of item i of theLink --extract full path
			set text item delimiters of AppleScript to {":"} --uses the colon as the new delimiter
			set theImageName to last text item of theImagePath --extract file name
			set text item delimiters of AppleScript to oriDelims --resets the old delimiters
			display dialog theImageName
		end repeat
	end tell
end tell

As you can see, I can easily extract the file name by coding “set theImageName to last text item of theImagePath”; but I couldn’t figure out how to extract the folder name by coding the 2nd last text item?
Please help! Thanks in advance!

Hi,

you can also refer to the last text item with text item -1,
the 2nd last text item is text item -2

Thanks for your prompt and great reply, StefanK!
I have been trying hard on the code to express the 2nd last text item for the whole day.
Thanks again!
