NTFS File System

Designed exclusively for use with the Windows NT and later operating systems. NTFS allows for stronger security and more flexible file management methods than does FAT. See also file allocation table (FAT).

A file system that provides performance, security, reliability, and advanced features that are not found in any version of the file allocation table (FAT) filesystem. For example, NTFS guarantees volume consistency by using standard transaction logging and recovery techniques. If a system fails, NTFS uses its log file and checkpoint information to restore the consistency of the file system. NTFS also provides advanced features, such as file and folder permissions, encryption, disk quotas, and compression.
