This process is called making a filesystem. Most UNIX filesystem types have a similar general structure, although the exact details vary quite a bit. The central concepts are superblock, inode , data block, directory block , and indirection block.
What are blocks in file system?
In computing (specifically data transmission and data storage), a block, sometimes called a physical record, is a sequence of bytes or bits, usually containing some whole number of records, having a maximum length; a block size. Data thus structured are said to be blocked.
What is a block in Unix?
The Unix file system allocates data blocks (blocks that contain a file’s contents) one at a time from a pool of free blocks. Unix uses 4K blocks. Moreover, a file’s blocks are scattered randomly within the physical disk. Inodes include pointers to the data blocks.

The most important purpose of a file system is to manage user data. This includes storing, retrieving and updating data. … The user program can read, write and update records without regard to their location. This requires complicated management of blocks of media usually separating key blocks and data blocks.
What are block sizes?
