Shell Scripting

So I've made a batch file to search the entire computer utilizing xcopy and copy these certain types of files to an external HDD.

Is there any way to force xcopy to just dump the files I want -without- building the directory structure?

I just want pictures in a pictures folder, docs in a doc folder, etc.

I don't want to have to sort through WINDOWS\System32\bla.jpg and Local Settings\App Data\Microsoft\<Whatever>\bla2.jpg to figure out what's junk and what's not. Here's the contents of my batch file so far.

@echo off
