Advantages of NTFS
Formatting Windows 2000 volumes with NTFS instead of FAT allows you to use
advanced features that are available only on NTFS, including the following:
NTFS is a recoverable file system. A user seldom needs to run a disk repair
program on an NTFS volume. NTFS guarantees the consistency of the volume by
using standard transaction logging and recovery techniques. In the event of
a system failure, NTFS uses its log file and checkpoint information to
automatically restore the consistency of the file system.
NTFS supports compression on volumes, folders, and files. Files that are
compressed on an NTFS volume can be read and written by any Windows-based
application without first being decompressed by another program;
decompression happens automatically during the file read. The file is
compressed again when it is closed or saved.
NTFS supports all Windows 2000 file system features.
NTFS does not restrict the number of entries in the root folder.
Windows 2000 can format volumes up to 2 terabytes with NTFS.
NTFS manages disk space more efficiently than FAT, using smaller clusters (4
KB for volumes up to 2 terabytes).
The boot sector is backed up to a sector at the end of the volume.
NTFS minimizes the number of disk accesses required to find a file.
On NTFS volumes, you can set permissions on shares, folders, and files that
specify which groups and users have access, and what level of access is
permitted. NTFS file and folder permissions apply to users working on the
local computer and to users accessing the file over the network from a
shared folder. You can also set share permissions that operate on network
shares in combination with file and folder permissions.
NTFS supports a native encryption system, EFS, that uses symmetric key
encryption in conjunction with public key technology to prevent unauthorized
access to file contents.
Reparse points enable new features such as volume mount points.
Disk quotas can be set to limit the amount of space users can consume.
NTFS uses a change journal to track changes made to files.
NTFS supports distributed link tracking to maintain the integrity of
shortcuts and OLE links.
NTFS supports sparse files so that very large files can be written to disk
while requiring only a small amount of storage space.
