6. Windows File System
A file system provides a way of organizing a drive. It specifies how data is stored
on the drive and what types of information can be attached to files—filenames,
permissions, and other attributes. Windows supports three different file
systems which are NTFS,FAT32 and exFAT. NTFS is the most modern file system
 NTFS is the most modern file system. Windows uses NTFS for its system drive
and, by default, for most non-removable drives.
 FAT32 is an older file system that’s not as efficient as NTFS and doesn’t support
as big a feature set, but does offer greater compatibility with other operating
systems.
 exFAT is a modern replacement for FAT32 and more devices and operating
systems support it than NTFS but it’s not nearly as widespread as FAT32.
