Sorting mp3 files based on Album ID3 Tags in Powershell

# This will read all the files of a given extention in a directory
# Create a subfolder based on the album id3 tag
# move all the files into the appropriate album sub folder
#
# This doesn't work on filenames that have square brackets, they will be skipped
# Files without album id3 tags will be left unmodified
#
# requires:
# taglib-sharp.dll found at http://download.banshee.fm/taglib-sharp/
#

#folderToSearch is the folder that has the files
$folderToSearch="E:\music\"
#taglibLocation is the location of the taglib-sharp.dll
$taglibLocation="C:\Program Files (x86)\taglib-sharp-2.1.0.0-windows\Libraries"
#fileExtension is the file extension of the files with the ID3 tags (eg: mp3, wma, etc)
$fileExtension="mp3"
