Rust Requires Chilkat v11.0.0+

Extract a Single ZIP Entry While Preserving Its Stored Path

See more Zip Examples

This example demonstrates how to use the ZipEntry.Extract method to extract a single entry from a ZIP archive.

The example first creates a ZIP archive containing a text file. It then re-opens the ZIP, finds the entry, and extracts it to a base directory.

The Extract method uses the relative path stored within the ZIP entry. Any required subdirectories are created automatically beneath the specified base directory.

Rust

// ------------------------------------------------------------
// First create a sample ZIP archive containing a small text file.

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

if zip.new_zip("c:/temp/sampleText.zip").is_err() {
    println!("{}", zip.last_error_text());
    return;
}

// Add a small text file from memory.
if zip.add_string("myApp/docs/hello.txt", "Hello from a ZIP entry!", "utf-8").is_err() {
    println!("{}", zip.last_error_text());
    return;
}

// Write the ZIP archive to disk and close it.
if zip.write_zip_and_close().is_err() {
    println!("{}", zip.last_error_text());
    return;
}

// ------------------------------------------------------------
// Now open the ZIP archive we just created.

let zip2 = chilkat::Zip::new();

if zip2.open_zip("c:/temp/sampleText.zip").is_err() {
    println!("{}", zip2.last_error_text());
    return;
}

// Find the entry by its stored ZIP path.
let entry = chilkat::ZipEntry::new();

if zip2.entry_of("myApp/docs/hello.txt", &entry).is_err() {
    println!("Entry not found.");
    return;
}

// Extract this single entry to the base directory:
// 
//     c:/temp/extracted
// 
// Because the entry's stored path is:
// 
//     myApp/docs/hello.txt
// 
// the file will be extracted to:
// 
//     qa_output/extracted/myApp/docs/hello.txt
// 
// The required subdirectories are created automatically.
if entry.extract("c:/temp/extracted").is_err() {
    println!("{}", entry.last_error_text());
    return;
}

zip2.close_zip();

println!("Entry extracted successfully.");
