File system can be defined as a data structure which is used by the operating system to store information regarding the folders and files on the hard disk. Windows OS supports internal hard drives, external hard drives, floppy disks, CD’s, memory cards, DVD’s and other external USB drives. The supported file system varies according to the storage device types. For e.g., Floppy disks and USB flash drives support FAT file system whereas internal and external hard drive uses FAT and NTFS file systems.
