Linux Partition File system

The operating system manages files and data through the file system, the disk or partition needs to create a file system before it can be used for the operating system, and the process of creating a file system is called formatting.

Devices without a file system are called bare devices (raw);

The common file system has FAT32,NTFS,EXT2,EXT3,EXT4,XFS,HFS and so on;

The main system under Windows is: NTFS;

The main file system under Linux is: EXT3,EXT4;

Common parameters:

-b Specifies the file system block size
