I used this to rename extensions, should work on folders too:

just replace the "00" part with "200"

Check out "man rename". An example

rename 'foo' 'bar' dir*

dir_foo1/ becomes dir_bar1/
dir_foo2/ becomes dir_bar2/

Lets say I have them 001, 002, 003 .. etc.. How can I rename them ... 1-001, 1-002, 1-003

For that specifically:
rename "" "1-" 0*

if you wanted to renaming inside the folders for say imagesr like akjs.jpg bigpacks.jpg etc and rename them to 1.jpg 2.jpg 3.jpg.

Code:

#!/bin/bash

i=1; 
shopt -s nullglob; 

for f in *.{jpg,jpeg,JPG,JPEG,gif,GIF,png,PNG}; do     
	ext="${f##*.}"; 
	ext=${ext,,}; 
	ext=${ext/jpeg/jpg};     
	mv -- "$f" "newfolder/$i.${ext}";     
	((i++)); 
done
