How Does File System Work in Linux?
Contents

The Linux filesystem unifies all physical hard drives and partitions into a single directory structure. It all starts at the top–the root (/) directory. All other directories and their subdirectories are located under the single Linux root directory.

What is the file system used by the Linux?

Linux. Linux supports numerous file systems, but common choices for the system disk on a block device include the ext* family (ext2, ext3 and ext4), XFS, JFS, and btrfs. For raw flash without a flash translation layer (FTL) or Memory Technology Device (MTD), there are UBIFS, JFFS2 and YAFFS, among others.

How does a file system work?

In the UNIX sense of the word, a file is an array of bytes. For most filesystems, it’s an array of disk blocks with some associated metadata. The main job of any filesystem is finding which blocks belong to a given file and which belong to no files (and so can be used for new files or appended to an existing file).
