is the MFT (master file table). NTFS stores a copy of the critical part of the MFT to
reduce the possibility of data damage and loss. All other NTFS data structures are
special files. NTFS stands for NT File System.

Like FAT, NTFS uses clusters to store files, but cluster size does not depend on
partition size. NTFS is a 64-bit file system. It uses unicode to store file names. It is
also a journaling (failure-protected) file system, and supports compression and
encryption.

Files in folders are indexed to speed up file search.

B.2.4 Linux

Ext2

Ext2 is one of the main file systems for the Linux operating system. Ext2 is a 32-bit
system. Its maximum size is 16TB. The main data structure that describes a file is
an i–node. A place to store the table of all i-nodes has to be allocated in advance
(during formatting).

B.2.5 Linux

Ext3

Ext3 is a journaling file system used by the Linux operating system. It is forward-
and backward-compatible with Linux Ext2. It has multiple journaling modes and
broad cross-platform compatibility in both 32- and 64-bit architectures.

B.2.6 Linux

ReiserFS

ReiserFS was officially introduced to Linux in 2001. ReiserFS overcomes many Ext2
disadvantages. It is a 64-bit journaling file system that dynamically allocates space
for data substructures.
