Detailed explanation-1: -In computing, a file system or filesystem (often abbreviated to fs) is a method and data structure that the operating system uses to control how data is stored and retrieved.
Detailed explanation-2: -An integral part of an OS is what is called a File System. A File System is a data structure that stores data and information on storage devices (hard drives, floppy disc, etc.), making them easily retrievable. Different OS’s use different file systems, but all have similar features.
Detailed explanation-3: -System files and data are kept in the computer system’s memory, and when these files are needed by an application, the operating system must have some way to read the memory and access the appropriate files. There are three file access methods in OS, sequential access, direct access, and indexed sequential access.
Detailed explanation-4: -A file structure is a combination of representations for data in files. It is also a collection of operations for accessing the data. It enables applications to read, write, and modify data. File structures may also help to find the data that matches certain criteria.
