# remove all jpeg image files of an expired modification date = mtime
# you could also use creation date (ctime) or last access date (atime)
# os.stat(filename) returns (mode, ino, dev, nlink, uid, gid, size, atime, mtime, ctime)
# tested with Python24 vegaseat 6/7/2005
import os, glob, time
root = 'D:\\Vacation\\Poland2003\\' # one specific folder
#root = 'D:\\Vacation\\*' # or all the subfolders too
# expiration date in the format YYYY-MM-DD
xDate = '2003-12-31'
print '-' * 50
for folder in glob.glob(root):
print folder
# here .jpg image files, but could be .txt files or whatever
for image in glob.glob(folder + '/*.jpg' ):
# retrieves the stats for the current jpeg image file
# the tuple element at index 8 is the last-modified-date
stats = os.stat(image)
# put the two dates into matching format
lastmodDate = time.localtime(stats[ 8 ])
expDate = time.strptime(xDate, '%Y-%m-%d' )
print image, time.strftime( "%m/%d/%y" , lastmodDate)
# check if image-last-modified-date is outdated
if expDate > lastmodDate:
try :
print 'Removing' , image, time.strftime( "(older than %m/%d/%y)" , expDate)
#os.remove(image) # commented out for testing
except OSError:
print 'Could not remove' , image
