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.

# Open an existing ZIP archive.
my $success = $zip->OpenZip('c:/temp/example.zip');

# A ZIP archive may contain zero entries.

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

$success = $zip->EntryAt(0, $entry);
if (!$success) {
    print $zip->LastErrorText, "\n";

# ------------------------------------------------------------
# Iterate through all ZIP entries.
#
# GetNext updates the same ZipEntry object so that it
# represents the next entry in the ZIP archive.

    if ($entry->IsDirectory) {
        print '[Directory] ', $entry->FileName, "\n";

    }

    # Advance to the next entry.
