Script to remove spaces from all file and folder names under a certain directory root.

space_remover.py

# space_remover.py
#
# Script to remove spaces at the end of folder or file names
# This is a problem when creating a folder on a platform other
# than Windows and sharing that folder with a Windows user
# The Windows user will then not be able to work with files
# within that folder.
# The solution is simply to remove the space at the end of
# the folder name, but this is not possible to do through
# the Windows GUI interface. Normal "CMD" also has problems.
# Thus, this script was born :)

# This script must be run in a unix like environment, such
# as Cygwin, Linux or OS X, as the normal Windows
# environment is not able to enter directories with a space
# at the end
