File Organization 

A file is a collection of records. You can access the records using the primary key.

File organization is the logical relationship between different records. This method defines how file records are mapped to disk blocks.

File organization is used to describe how records are stored in the form of blocks and the blocks are arranged on the storage medium. 

The first way to map a database to files is to use multiple files and store only one fixed-length record in a particular file. 

Another way is to structure the file so that it can contain records of multiple lengths. A
file with fixed-length records is easier to implement than a file with variable-length records.
