Zip and Unzip

Introduction

This sample demonstrates the use of @ohos.zlib. Below shows the sample app.

Concepts

Zip: compresses a file or folder based on the passed file path to zip and the path of the zipped file.

Unzip: decompresses a file or folder based on the passed file path to unzip and the path of the unzipped file.

Required Permissions

Usage

1. Touch + in the upper right corner of the sample app.

2. In the Create file dialog box displayed, enter the file name and content, and touch OK.

3. The file created is displayed on the home page. Touch Zip. A message is displayed, indicating that the file is compressed, and a .zip file with the same name is created in the file list.

4. Touch Unzip next to the zipped file. A message is displayed, indicating that the file is decompressed, and a folder with the same name is created in the file list.

Constraints

1. This sample can only be run on standard-system devices.

2. This sample requires DevEco Studio 3.1 Canary1 (Build Version: 3.1.0.100, built on November 3, 2022) to compile and run.

3. The paths passed in the Zip and Unzip APIs must be the relative paths obtained by the context API. Currently, Zip and Unzip support operations only on files in the app directory.
