(CkPython) Iterate Over ZIP Entries Using EntryAt

This example demonstrates how to use the EntryAt method to iterate over all entries contained within a ZIP archive.

The EntryAt method retrieves a ZipEntry object for a given zero-based index.

This is useful for:

• Enumerating all entries in a ZIP archive
• Inspecting filenames, sizes, and timestamps
• Searching or filtering ZIP contents

Suppose the ZIP archive contains:

docs/readme.txt
images/logo.png
data/config.json

The example loops through all ZIP entries and prints information about each entry.

Note: This example requires Chilkat v11.0.0 or greater.

import sys
import chilkat

success = False

success = False

# Open an existing ZIP archive.
zip = chilkat.CkZip()

success = zip.OpenZip("example.zip")
if (success == False):
    print(zip.lastErrorText())
    sys.exit()

# Get the total number of entries in the ZIP archive.
numEntries = zip.get_NumEntries()

print("Number of ZIP entries = " + str(numEntries))

# Create a ZipEntry object that will be reused
# for each entry retrieved by EntryAt.
entry = chilkat.CkZipEntry()

# Iterate over all ZIP entries.
i = 0
while i < numEntries :

    # Retrieve the entry at index i.
    success = zip.EntryAt(i,entry)
    if (success == False):
        print(zip.lastErrorText())
        sys.exit()

    print("Entry " + str(i))
    print("  FileName: " + entry.fileName())
    print("  Uncompressed Length: " + str(entry.get_UncompressedLength()))
    print("  Compressed Length: " + str(entry.get_CompressedLength()))
    print("")

    i = i + 1

# Sample output:
# 
# Entry 0
#   FileName: docs/readme.txt
#   Uncompressed Length: 1204
#   Compressed Length: 512
# 
# Entry 1
#   FileName: images/logo.png
#   Uncompressed Length: 84211
#   Compressed Length: 84102

zip.CloseZip()

print("Done.")
