# Generating a Sandbox File with One Click

## Overview

This sample showcases one-click generation of the sandbox file, user preferences, KV store based on the **fileIo**, **distributedKVStore**, **preferences**, and **relationalStore** APIs.
The RDB store file function facilitates file transfer between the device and the computer.

## How to Use

1. Tap the Generate File button to generate an application file and a database file on the device.

2. Tap the File List button to view the names and types of the files generated on the device.

### How to Implement

1. The **fileIo**, **distributedKVStore**, **preferences**, and **relationalStore** APIs are used to generate an application file and a database file in the sandbox directory of the device.

2. You can search for the corresponding file name in the sandbox directory to check whether the file is generated.
