(CkPython) Zip Files in a Date Range

See more Zip Examples

Demonstrates how to use the Zip.MinDate and Zip.MaxDate properties to zip only those files with a last-modified date within a date range.

Note: This example requires Chilkat v10.0.0 or greater.

import sys
import chilkat

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

zip = chilkat.CkZip()

zipPath = "c:/temp/qa_output/out.zip"

# Initialize the zip object with the path of the .zip to be created.
zip.NewZip(zipPath)

# The MinDate and MaxDate properties use the timestamp date/time string format.
# Here are some examples:
# YYYY-MM-DD (e.g., 2024-07-31)
# YYYY-MM-DDTHH:MM:SS�HH:MM (e.g., 2024-07-31T12:34:56+02:00)
# 2024-07-31T12:34:56Z (the "Z" denotes Zulu time, or UTC)

# Only append files having a last-modified date greater than 1-Jan-2017
zip.put_MinDate("2017-01-01T00:00:00Z")

# Also, only append files having a last-modified date less than the end of 2020
zip.put_MaxDate("2020-12-31T23:59:59Z")

# You don't need to specify both MinDate and MaxDate.
# You can specify only one or the other if needed.

# The MinDate/MaxDate properties apply to all of the Chilkat methods for appending files.

# Recursively append to the zip object the paths of the files and directories in a directory tree.
# At this point we are not creating the .zip, nor are we reading the contents of the files.
# We are simply appending references to the files and directories in the local filesystem
# that will get processed when WriteZip is called.
