This is the tree in the folders:
In this tree under the LV1 folder there are images named: img01.jpg/img02.jpg/img03.
jpg etc. upto img20.jpg
I want to rename the images to: 4B-MiniMatic-2-1mm-adj-AR2
g uptil _20.jpg
I attached a listing of the folders within the main folder. Can a batch file be used to do this or is there a third party app I can use?
