# Zip and Unzip

### Overview

This sample uses the interfaces provided by @ohos.zlib and @ohos.fileio to add, zip, and unzip files.

### Preview

| Home page                              | Dialog box                              |

### How to Use

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 with the extension .txt is displayed in the list on the home page, and the physical address of the file is **/data/app/el2/100/base/ohos.samples.ziplib/haps/entry/files/**. Touch **Zip**. A message is displayed, indicating that the file is compressed successfully. A .zip file with the same name is created in the file list.

4. Touch **Unzip** next to the compressed file. A message is displayed, indicating that the file is decompressed successfully. A folder with the same name is created in the file list.

### How to Implement

The interfaces for adding, zipping, and unzipping files are called on the home page. For details about the source code, see [Index.ets](entry/src/main/ets/pages/Index.ets).
* Adding a file: Call **fileio.openSync()** to create a file and call **fileio.writeSync()** to write content to the file.
* Zipping a file: Call **zlib.zipFile()** to zip a file.
* Unzipping a file: Call **zlib.unzipFile** to unzip a file.
