(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
Officially introduced with its version 7.2 of the Linux operating system, Ext3 is the
Red Hat Linux journaling file 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.
