A superblock is a collection of metadata used to show the properties of file systems in some types of operating systems. The superblock is one of a handful of tools used to describe a file system along with inode, entry and file.
The superblock essentially records a file system’s characteristics – block size, other block properties, sizes of block groups and location of inode tables. The superblock is especially useful in UNIX and similar operating systems where a root directory contains a variety of subdirectories. The inode stores other file metadata, excluding its name and actual contents.
