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.

Rust

let mut success = false;

let zip = chilkat::Zip::new();

// Open an existing ZIP archive.
success = zip.open_zip("c:/temp/example.zip").is_ok();
if !success {
    println!("{}", zip.last_error_text());
    return;
}

// A ZIP archive may contain zero entries.
if zip.num_entries() == 0 {

    println!("The ZIP archive is empty.");

    zip.close_zip();
    return;
}

// ------------------------------------------------------------
// Get the first ZIP entry.
// 
// EntryAt(0,entry) initializes the ZipEntry object so that
// it represents the first entry in the ZIP archive.
// 
let entry = chilkat::ZipEntry::new();

success = zip.entry_at(0, &entry).is_ok();
if !success {
    println!("{}", zip.last_error_text());
    return;
}

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

    if entry.is_directory() {

        println!("[Directory] {}", entry.file_name());

    } else {

        println!("[File] {}", entry.file_name());
    }

    // Advance to the next entry.
    success = entry.get_next().is_ok();
}

zip.close_zip();

println!("Done.");
