Usually the larger the cluster size the greater disk space losses (waste) become. For
more detailed information about cluster size management see paragraph 2.6
The FAT16 file system, like many others, has a root folder. But unlike all
others its root folder is stored in a special place and is limited in size
(standard formatting creates a root folder with 512 entries). Acronis OS
Selector Disk Administrator allows you to change the size of the root folder
for an existing partition.

Initially FAT16 had file name limitations of 8 characters in name and 3
characters in extension, but long file name support in Windows 95 and
Windows NT eliminated this limitation. OS/2 also supports long names, but in
another way. Yet another is used in UMSDOS file system that allows the
Linux operating system to work on FAT disks.

2.3.2 FAT32
FAT32 operating system first appeared in Windows 95 OSR2 and is also
supported in Windows 98/ME and Windows 2000/XP. FAT32 is an extension
of FAT16. FAT32 mainly differs from FAT16 by 28-bit cluster numbers and
more flexible root folder that is no longer limited in size. The reason for
creating FAT32 was the need to support large (more than 8 gigabytes) hard
disks and the impossibility of building more complicated file system into
MS-DOS that remains the base for Windows 95/98/ME.

Maximum FAT32 file system size is 2 terabytes.
2.3.3 NTFS
NTFS is the basic Windows NT/2000/XP file system. Its organization is kept
secret, so no other operating system fully supports it. Basic NTFS structure is
an MFT (Master File Table). NTFS stores a backup copy of the MFT’s critical
part to decrease the probability of data damage and loss. All other NTFS data
structures are special files (metafiles).

structures are special files (metafiles).
NTFS, like FAT, uses clusters to store files, but cluster size is independent
from partition size. NTFS is a 64-bit file system; it uses Unicode to store file
names, with a journaling (or so-called failure-proof) file system, that
supports compression and encryption.

Files in folders are indexed to speed up search routines.

Ext2
Ext2 is the basic file system for the Linux operating system. Ext2 is a 32-bit
file system, its maximum size is 16 terabytes. The basic data structure, which
describes a file, is an I-node. Area to store the table of all I-nodes should be
allocated in advance (during formatting). Acronis OS Selector Disk
