Unzip Newer

 Chilkat Python Module Downloads for Windows, Linux, and MAC OS X

Python script to unzip only files with a more recent last-modified date/timestamp than the corresponding file on disk.

# file: UnzipNewer.py

import chilkat

# Unzip files that have a more recent last-modified date/timestamp
# than the corresponding file on disk.
zip = chilkat.CkZip()
zip.UnlockComponent("anything for 30-day trial")

success = zip.OpenZip("exampleData.zip")
if success:
	# Returns -1 if error, otherwise returns the number of files unzipped.
	
	# In this example, UnzipNewer will create the directory "unzipDir" in the current
	# working directory (if it does not already exist) and unzip into it.
	numUnzipped = zip.UnzipNewer("unzipDir")
	print "numUnzipped = " + str(numUnzipped) + "\n"
else:
	# Failed to open the .zip archive.
	zip.SaveLastError("openZipError.txt")
