Moving a file and its changed path

So I have a crappy Windows computer where I store all my files. Occassionally, I like to retrieve them and I’m using this:

on run {input, parameters}
	repeat with thisitem in input
		tell application "Finder"
			set the itempath to the quoted form of the POSIX path of thisitem
			if thiskind = "single" then
				do shell script ("mv -n " & itempath & " ~/Desktop/Procrastination/Boo-urns")
				-- HERE'S my problem: --
				tell application "iFlicks"
					import thisitem without gui
				end tell
				-- --
			else if thiskind = "compressed" then
				-- uncompress, then import...
				-- do nothing
			end if
		end tell
	end repeat
end run

So I move the file to local and then I want to import it into an iTunes processing app. But obviously the path is now different. It’s no longer on the network drive, it’s on my HDD.

How do I change the path (but keep the file’s name)?

(Or have I done this the wrong/long way?)

Get the name of the input file before you move it, and since you know the destination, just concatinate that and the name. To revert from ~/Desktop/Procrastination/Boo-urns to Finder coordinates, set newFile to (posix file ~/Desktop/Procrastination/Boo-urns) as alias.
