Quick script to use WIT (http://wit.wiimm.de/) to move Wii (WBFS) backup files to a standard directory structure. Works with standard .wbfs files on a FAT/NTFS filesystem, for example.
require 'fileutils'
# Set the directory containing your backup files (they can be in sub-directories of this path)
f = Dir.glob './**/*.wbfs'
f.each do |n|
x = `wwt LIST \"#{n}\"`
if $?.success?
# WBFS containers can have multiple games in them. Here, we select just the first one for naming.
# Nearly always, you will have only backed up a single game per container anyway.
(id, name) = x.split("\n")[3].split(/\s{2,}/)
