Dart Requires Chilkat v11.0.0+

Exclude Multiple Directories When Adding Files to a ZIP

See more Zip Examples

This example demonstrates how to use the ExcludeDir method to exclude specific directory names when recursively adding files to a ZIP archive.

The ExcludeDir method excludes directories by name. Any directory matching an excluded name is skipped entirely, including all files and subdirectories beneath it.

This is useful for excluding directories such as:

• .git
• node_modules
• bin
• obj
• Temporary or cache directories

Call ExcludeDir once for each directory name to exclude.

Suppose the local filesystem contains:

c:/project/src/main.cpp
c:/project/src/util.cpp
c:/project/bin/app.exe
c:/project/obj/main.obj
c:/project/.git/config
c:/project/node_modules/library/index.js

After excluding bin, obj, .git, and node_modules, only the files beneath src are added to the ZIP archive.

The resulting ZIP archive contains:

project/src/main.cpp
project/src/util.cpp

Dart

import 'package:chilkat/chilkat.dart';

void main() {
  final zip = CkZip();

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

  // Exclude several directory names.
  // 
  // Any directory matching one of these names will be skipped
  // during recursive file appending.
  zip.excludeDir('bin');
  zip.excludeDir('obj');
  zip.excludeDir('.git');
  zip.excludeDir('node_modules');

  // Recursively append all files beneath c:/project.
  // 
  // Because saveExtraPath = true, the ZIP paths will
  // include "project/" as the leading directory.
  final recurse = true;
  final saveExtraPath = true;
  final archiveOnly = false;
  final includeHidden = true;
  final includeSystem = false;

  try {
    zip.appendFilesEx('c:/project', recurse, saveExtraPath, archiveOnly, includeHidden, includeSystem);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Write the ZIP archive.
  try {
    zip.writeZipAndClose();
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print('ZIP archive created successfully.');
}
