Zip a Directory Tree

See more Zip Examples

Demonstrates how to zip an entire directory tree into a .zip archive. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  final zip = CkZip();

  try {
    zip.newZip('test.zip');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Append a directory tree.  The call to AppendFiles does
  // not read the file contents or append them to the zip
  // object in memory.  It simply appends references
  // to the files so that when WriteZip or WriteZipAndClose 
  // is called, the referenced files are streamed and compressed
  // into the .zip output file.

  final recurse = true;
  try {
    zip.appendFiles('c:/temp/a/*', recurse);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  try {
    zip.writeZipAndClose();
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print('Zip Created!');
