(AutoIt) 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.
