Windows BAT file for deleting the files in a Git repo based on patterns in the .gitignore. This file is designed to be run in a parent directory with multiple Repo folders within it. You can run bat file with -y flag to Automatically confirm deletions but I'd recommend doing the Yes/No confirm for each file as the patterns can be unpredictable and nothing goes to the Recycle bin, all permanent deletes. If your .gitignore has many complex paths with wildcards, might do a quick comment out of those before running.
