macOS automator help with creating new folders, or maybe a script?

[nicolanicola]

I have a folder structure as follows all items>item name>item colour>files.

Now in this item colour folder are 2 files, a large sized image and a thumbnail version of that image. I need to create a folder in here called thumbnail and move the thumbnail image into it. Can I do this with automator?

I have maybe about 30 item name folders with various amounts of folders within each of those.

If I was to say what it was in code terms it'd be for every folder in all items,open folder then go in every folder in here and create a directory called thumbnail and move the file named closeupTN.jpg into here.

I've attached a folder structure. It starts from the contents of 'all items' in the above description.

Try this little script

I assume all items is a folder? Choose this toplevel folder in the choose folder dialog when you run the script.

set the_folder to (choose folder with prompt "Choose your “all items“ folder")
set FilenamesList to paragraphs of (do shell script "find " & quoted form of POSIX path of the_folder & " -type f -name *TN.jpg")
repeat with i from 1 to count of FilenamesList
	set thisFileObject to (POSIX file (item i of FilenamesList) as alias)
	-- do something with the file object "thisFileObject"
	tell application "Finder"
		try
			set tumbnailFolder to make new folder in container of thisFileObject with properties {name:"thumbnail"}
			move thisFileObject to tumbnailFolder
		on error errMsg number errNumber
			display alert errMsg message errNumber
		end try
	end tell
end repeat
