Extract a .tar.gz Archive to a Directory

See more Gzip Examples

This example demonstrates how to use the UnTarGz method to extract a .tar.gz archive to a specified directory.

The method performs both the Gzip decompression and TAR extraction in a single step. It operates in streaming mode, meaning it does not create temporary files and uses a constant, minimal amount of memory regardless of archive size.

The bNoAbsolute parameter is set to _TRUE_ in this example to prevent extraction of files with absolute paths. This is a safety measure that helps avoid overwriting files in unintended locations (such as system directories).

This method is ideal for efficiently extracting large .tar.gz archives while maintaining security and low memory usage.

React Native

import { Gzip } from '@chilkat/react-native'

async function chilkatExample() {
  // This example demonstrates how to extract a .tar.gz archive to a directory.

  const gzip = new Gzip();

  // The .tar.gz file to be extracted:
  const tgzPath = 'c:/temp/archive.tar.gz';

  // The destination directory:
  const destDir = 'c:/temp/outputDir';

  // Set to true to prevent extraction of files with absolute paths:
  const noAbsolute = true;

  // Extract the archive:
  try {
    await gzip.unTarGzAsync(tgzPath, destDir, noAbsolute);
  } catch {
    console.log(gzip.lastErrorText);
    return;
  }

  console.log(`Archive successfully extracted to: ${destDir}`);
