Quick and dirty script to sort pictures into a directory structure based on EXIF DateTaken date/times.

sort.py

import os
import EXIF
import datetime

work_dir = '../pics'

exif_date_format = '%Y:%m:%d %H:%M:%S'
for dirname, dirnames, filenames in os.walk(work_dir):
    for filename in filenames:
        old_file_path = os.path.join(work_dir, filename)
        file = open(old_file_path, 'rb')
        tags = EXIF.process_file(file, stop_tag='Image DateTime')
        if 'Image DateTime' in tags:
            dt = datetime.datetime.strptime(tags['Image DateTime'].values, exif_date_format)
            dir = dt.strftime('path/%Y/%m/%Y-%m-%d/')
            if not os.path.exists(dir):
                os.makedirs(dir)
            new_file_path = os.path.join(dir, filename)
            os.rename(old_file_path, new_file_path)
        file.close()

Badly named variables and posiable exceptions on the makedirs, and I'm sure other places. But it does at least sort out my DCIM dir.

Uses exif-py.
