What are the common file systems that Linux operating systems support?

It is often possible to use an operating system (such as Windows and Linux) because of the need for work or learning. The file systems supported by Windwos may be familiar, and the file systems supported by the Linux operating system may be unfamiliar. It is often necessary to copy files from Windows to the Linux system, which requires understanding the file systems supported by the Linux operating system. The following is a brief description of the main concerns of several commonly used file systems supported by the Linux operating system, such as the limit of individual file sizes and the maximum capacity supported by the file system.

1, Linux operating system using Virtual file system (VFS) up and user process file access system call interface, down and specific different file system implementation interface. The VFS masks the implementation details of specific files and provides a unified operational interface up. The VFS enables arbitrary file systems that can be accessed through file access system calls. So Linux system core can support more than 10 kinds of file system types, such as Btrfs, JFS, ReiserFS, ext, ext2, ext3, Ext4, ISO9660, XFS, Minx, MSDOS, Umsdos, VFAT, NTFS, HPFS, NFS, SMB, SysV, Proc, and so on. Some of the important file systems that it supports are described below

2, ext specially designed for Linux, the Linux core for the first file system. Single file maximum limit: unknown; the file system supports up to 2GB of capacity.

3, ext2 by Rémy Card design, in lieu of ext, Linux kernel is used by the file system. A single file has a maximum limit of 2TB; the file system supports 32TB capacity.

4, ext3 a log file system. A single file has a maximum limit of 16TB, which supports a maximum of 32TB capacity.

5, Ext4theodore TSO led the development team to achieve, Linux system under the log file system. A single file has a maximum limit of 16TB, which supports a maximum of 1EB capacity.

6, JFS2 a byte-level log file system, which is mainly designed and developed to meet the high throughput and reliability requirements of the server. A single file has a maximum limit of 16TB, which supports a maximum of 1PB capacity.

Note: Only the maximum size of the file system and the maximum capacity of the file system are described here, and the performance comparison is not indicated.
