本书把文件系统中的文件氛围了5个范畴

1. File System Category 文件系统范畴,存储了文件系统的一些控制模块的地址和布局

(The file system category contains the general data that identify how this file system is unique and where other important data are located.)

2. Content Category 内容范畴,存储了具体文件和目录的地址

(The content category includes the storage locations that are allocated to files and directories so that they can save data.)

3. Metadata Category 元数据范畴,记录每个文件的一些描述和控制信息

(The metadata category is where the descriptive data reside.)

4. File name Category 文件名范畴,方便用户按名字管理

(The file name category includes the names of files, and it allows the user to refer to a file by its name instead of its metadata address.)

5、 Application Category 应用范畴,提供一些额外的辅助文件系统管理的数据

(These data are not essential to the file system, and they typically exist as special file system data instead of inside a normal file because it is more efficient. This section covers one of the most common application category features, which is called journaling.)
