# System Storage Statistics

### Overview

This sample shows how to use APIs for obtaining the storage information of an app and a file system.

1. App storage statistics: provides APIs for obtaining storage space information, including the space of built-in and plug-in memory cards, space occupied by different types of data, and space of app data.
2. File system storage statistics: provides APIs for obtaining storage information of a file system, including the total size and free size of a file system, in bytes.
