What is File System?
A filesystem is the methods and data structures that an operating system uses to keep track of files on a disk or partition; that is, the way the files are organized on the disk. The word is also used to refer to a partition or disk that is used to store the files or the type of the filesystem.
1) The file system allows the user to define files and directories so that disk space can be allocated and de-allocated to each file.
2) The operating system uses files for information storage. Files are mapped by the operating system onto physical devices
3) A file is a collection of related information. Each file is having name and extension depending upon file type.
