Unzip Files in a Date Range

See more Zip Examples

Demonstrates how to use the Zip.MinDate and Zip.MaxDate properties to unzip only those files with a last-modified date within a date range.

Note: This example requires Chilkat v10.0.0 or greater.

React Native

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

async function chilkatExample() {
  // This example assumes the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  const zip = new Zip();

  try {
    await zip.openZipAsync('qa_data/zips/sample.zip');
  } catch {
    console.log(zip.lastErrorText);
    return;
  }

  // The MinDate and MaxDate properties use the timestamp date/time string format.
  // Here are some examples:
  // YYYY-MM-DD (e.g., 2024-07-31)
  // YYYY-MM-DDTHH:MM:SS�HH:MM (e.g., 2024-07-31T12:34:56+02:00)
  // 2024-07-31T12:34:56Z (the "Z" denotes Zulu time, or UTC)

  // Only unzip files having a last-modified date greater than 1-Jan-2017
  zip.minDate = '2017-01-01T00:00:00Z';

  // Also, only unzip files having a last-modified date less than the end of 2020
  zip.maxDate = '2020-12-31T23:59:59Z';

  // You don't need to specify both MinDate and MaxDate.
  // You can specify only one or the other if needed.

  // The MinDate/MaxDate properties apply to all of the Chilkat methods for unzipping.

  const numUnzipped = await zip.unzipAsync('c:/temp/unzipDir');
  if (numUnzipped < 0) {
    console.log(zip.lastErrorText);
    return;
  }

  zip.closeZip();
