# copy all image files of the form "yyyy-mm-dd..." to their corresponding
# directories (those being tgtDir/yyyy/mm/dd)
# useful for cleaning the Dropbox camera upload directory
#
# notice: this script doesn't delete any file, it just creates copies
#
# initial setup:
# - srcDir - where all the files are
# - tgtDir - parent directory for creating the yyyy/mm/dd directories

import sys, os, shutil

# fill these two!
srcDir = ""
tgtDir = ""

if srcDir == "" or tgtDir == "":

	sys.exit

		# make sure the file doesn't already exist in the target,
		# or print an error and move on (don't copy)
