My Python script to sort file based on its MIME type into separate folders.

file_type_sorter.py

# This is a Python script that let you arrange
# files into a folder for each extension. Actually
# I lied, this script is not about file extension
# but about a file's mime type. So, in case there
# are files that has no extension this script can
# predict what the file's extension could be.
# However, the only requirement is that file need
# to be able to be read by the computer's OS. For
# example image files usually has no problem with
# this script also with other media files. But,
# uncommon file type will have a problem.
# Especially, if the computer does not how to open
# the files.THIS IS A PYTHON3 CODES. PYTHON MAGIC
# LIBRARY DOES NOT WORKING WITH PYTHON2.
