# Bulk Folder Rename Script (Windows Batch)

Simple batch script to rename all folders matching a pattern.
Uses delayed variable expansion for inline string replacement.

Everywhere where you see an xxxxx put an old part of the folder name, this script will rename all the folders in yyyy or refactor this part of the file name
