Extract ZIP Files Without Preserving Directory Paths Using DiscardPaths

See more Zip Examples

This example demonstrates how to use the DiscardPaths property to extract files from a ZIP archive without recreating the stored directory structure.

When DiscardPaths is set to _TRUE_, all extracted files are written directly into the target extraction directory, and any stored ZIP path information is ignored.

This is useful when:

• Flattening ZIP contents into a single directory
• Ignoring stored subdirectory structures during extraction
• Extracting only the files themselves without recreating folders

Suppose the ZIP archive contains:

docs/readme.txt
docs/manual.pdf
images/logo.png

Normally, extracting the ZIP would create:

output/docs/readme.txt
output/docs/manual.pdf
output/images/logo.png

But when DiscardPaths is set to _TRUE_, the extracted files become:

output/readme.txt
output/manual.pdf
output/logo.png

The stored ZIP directory paths are discarded during extraction.

React Native

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

async function chilkatExample() {
  const zip = new Zip();

  // Open an existing ZIP archive.
  try {
    await zip.openZipAsync('example.zip');
  } catch {
    console.log(zip.lastErrorText);
    return;
  }

  // Discard stored ZIP paths during extraction.
  // 
  // When DiscardPaths = true, all files are extracted
  // directly into the target directory without recreating
  // the ZIP directory structure.
  zip.discardPaths = true;

  // Extract all files to the output directory.
  // 
  // Even if the ZIP contains:
  // 
  //     docs/readme.txt
  //     docs/manual.pdf
  //     images/logo.png
  // 
  // The extracted files become:
  // 
  //     c:/output/readme.txt
  //     c:/output/manual.pdf
  //     c:/output/logo.png
  // 
  const numFilesUnzipped = await zip.unzipAsync('c:/output');

  if (numFilesUnzipped < 0) {
    console.log(zip.lastErrorText);
    return;
  }

  console.log(`Number of files extracted = ${numFilesUnzipped}`);

  zip.closeZip();

  console.log('Files extracted successfully.');
