Iterate Through ZIP Entries Using EntryAt and ZipEntry.GetNext

See more Zip Examples

This example demonstrates how to iterate through all entries in a ZIP archive using:

• Zip.EntryAt to obtain the first entry
• ZipEntry.GetNext to advance through the remaining entries

The example prints each ZIP entry's stored filename and whether the entry is a file or directory.

This approach is useful when sequentially processing ZIP entries without repeatedly calling EntryAt by index.

Suppose the ZIP archive contains:

docs/
docs/readme.txt
images/logo.png
hello.txt

The example iterates through each entry in the order stored within the ZIP archive.

CkPython

import sys
import chilkat

success = False

zip = chilkat.CkZip()

# Open an existing ZIP archive.
success = zip.OpenZip("c:/temp/example.zip")
if (success == False):
    print(zip.lastErrorText())
    sys.exit()

# A ZIP archive may contain zero entries.
if (zip.get_NumEntries() == 0):

    print("The ZIP archive is empty.")

    zip.CloseZip()
    sys.exit()

# ------------------------------------------------------------
# Get the first ZIP entry.
# 
# EntryAt(0,entry) initializes the ZipEntry object so that
# it represents the first entry in the ZIP archive.
# 
entry = chilkat.CkZipEntry()

success = zip.EntryAt(0,entry)
if (success == False):
    print(zip.lastErrorText())
    sys.exit()

# ------------------------------------------------------------
# Iterate through all ZIP entries.
# 
# GetNext updates the same ZipEntry object so that it
# represents the next entry in the ZIP archive.
# 
while (success == True) :

    if (entry.get_IsDirectory() == True):

        print("[Directory] " + entry.fileName())

    else:

        print("[File] " + entry.fileName())

    # Advance to the next entry.
    success = entry.GetNext()

zip.CloseZip()

print("Done.")
