Overview of NTFS file system

New Technology File System (NTFS) is a proprietary journaling file system developed by Microsoft and it replaces File Allocation Table (FAT) and High-Performance File System (HPFS) as the default file system.

It helps to store the file information, including file name, size, storage location, creation date, access date, metadata change, etc. And it also maintains memory, encrypts data, regulates access to files, and ensures data security. And it has made some improvements in the following:

• Support for a long file name, up to 255 characters, not case sensitive and compatible with special characters, excluding ?, ", /, \.
• Store files as large as 16 exabytes and up to 8 petabytes volumes. An exabyte is 1000 times larger than 1 petabytes (1024 terabytes).
• Compress or decompress file in a drive, directory or directory tree individually, up to 4KB cluster size.
• Since server 2012 R2 or Windows 8 (both 32 and 64 bit), NTFS partition supports Bitlocker drive encryption with a trusted platform module(TPM).
• Use sparse files as a way to store disk space. The default value of it is zero and you can convert it into "real blocks" with null bytes, so as to store large files, even when there is not enough space.
• Monitor or control disk space for individual users easily with the help of disk space quotas.
