यहां एक या कई फ़ोल्डरों में स्थित zipfiles का परीक्षण करने के लिए पायथन में एक स्क्रिप्ट के नीचे है। मैंने इसे विंडोज 7 SP1 x64 अल्टीमेट पर परीक्षण किया है, लेकिन मुझे उम्मीद है कि यह किसी भी OS पर काम करेगा।
आउटपुट का उदाहरण:
Total time spent was 577.64 seconds, checking 100 files, totaling 77.06 GB,
among which 0 were corrupted.
स्क्रिप्ट:
'''
Test if the zip files are not corrected
'''

from __future__ import division
import sys
import zipfile
import glob
import os
import time
def test_zipfile(filepath):
'''
Test whether a zipfile is valid

start_time = time.time()
filesize = os.path.getsize(filepath)
print('Starting testing file: {0} ({1:.2f} MB)'.format(filepath,filesize/10**6), end='')
the_zip_file = zipfile.ZipFile(filepath)
ret = the_zip_file.testzip()
time_spent = time.time() - start_time
print('\tTest ended. Time spent: {0:.2f} s'.format(time_spent))
if ret is not None:
print("First bad file in zip {0}: {1}".format(filepath,ret))
is_valid = False
else:
#print "Zip file is good."
is_valid = True
return is_valid, time_spent, filesize
