    File System API guide

    这是一个实验中的功能
    此功能某些浏览器尚在开发中,请参考浏览器兼容性表格以得到在不同浏览器中适合使用的前缀.由于该功能对应的标准文档可能被重新修订,所以在未来版本的浏览器中该功能的语法和行为可能随之改变.

    The File System API simulates a local file system that web apps can navigate around. You can develop apps that can read, write, and create files and directories in a virtual, sandboxed file system.

    The asynchronous API methods return without blocking the calling thread. The asynchronous API doesn't give you data by returning values; instead, you have to pass a callback function. The synchronous API is intended to be used inside WebWorkers.

    For an overview of the File System API, see the following articles:
