What is the difference between FAT32 and NEFS file systems?

FAT32 is suitable for DOS,,Win95,,Win98 and other old systems and corresponding software use,Good compatibility,For example, NTFS cannot recognize files under DOS。

The disadvantage is that it wastes space and does not support a single file above 4G.

And NTFS supports large files above 4G

FAT32 is a backward partition format, the partition capacity is limited, and the NTFS format is relatively new and recommended for systems that do not support NT kernels.

The differences between the two formats are described below:

The difference between NTFS and FAT32.

Since the birth of the Windows series, its disk formats have ranged from FAT16, VFAT, FAT32, to NTFS. What now? I would like to introduce the features and differences of these four formats.

fat16: A file allocation table system, each partition can have a maximum of 65525 clusters. It can manage up to 2GB partitions and naming conventions, and cannot support advanced fault tolerance of the system.

As the capacity of the hard disk or partition increases, each cluster occupies more and more of the capacity, resulting in waste of hard disks!! Where Windows 95 must use FAT16.

VFAT is an extended (FAT) file system with file names up to 255 characters long.

FAT32: Support up to 2TB, which can save hard disk space.

NFTS: Microsoft Windows NT kernel system operating system support, a disk format specially designed for network and disk quota management, file encryption, etc. NTFS is also a cluster.

Save data for units. However, the NTFS cluster size does not depend on the disk size, and the cluster size reduction not only reduces the waste of disk space, but also reduces the possibility of disk fragmentation.

98, 98SE and XP 2000 2003 32GB

Windows NT 200 XP can only recognize NTFS system, Windows 9X Me and DOS cannot support NFT disks.

NFTs are safe and suitable for business but are the same for home use.

NTFS is generally always in the C disk, that is, the system disk, and other disks generally use FAT32. It seems that when there is no disk, it must be NTFS

1. Document Allocation Table (FAT):

A file system for MS-DOS and other Windows operating systems to organize and manage files.

A File Allocation Table (FAT) is a data structure created by Windows when you format a particular volume using the FAT or FAT32 file system.

Windows stores file-related information in FAT for later use when retrieving files.

2、fat32 ：

A file system that derives from the File Allocation Table (FAT) file system.

Compared to FAT, FAT32 is able to support smaller clusters and larger capacities, allowing for more efficient allocation of disk space on FAT32 volumes.

3. NTFS file system:

An advanced file system that delivers the performance, security, reliability, and advanced features not found in a variety of FAT editions.

For example, NTFS ensures volume consistency through standard transaction log functionality and recovery techniques. In the event of a system failure, NTFS is able to use log files and checkpoint information to restore file system consistency.

It can store a single file larger than 4G; Good security, and support encryption, convenient disk quota function; It can effectively reduce disk fragmentation; Compress files to reduce footprint.

(1) More secure file security, providing file encryption, can greatly improve the security of information.

2) Better disk compression.

3) It supports large hard disks up to 2TB, and as the disk capacity increases, the performance of NTFS does not decrease like FAT.

4) Individual files and folders can be granted permissions. Different users can assign different permissions to the same file or folder. In the NTFS file system, permissions can be set for individual users.

5) The recoverability of the NTFS file system is designed without requiring the user to run disk repair procedures in the NTFS volume. In the event of a system crash, the NTFS file system uses log files and checkpoint information to automatically restore the consistency of the file system.

6) The b-tree structure of the NTFS folder makes it possible for users to access files in larger folders even faster than files in smaller folders in the volume.

7) Individual files and folders can be compressed in NTFS volumes. The compression mechanism of the NTFS system allows users to read and write compressed files directly without the need to use decompression software to convert these files.

8) Support Active Directory and Domains. This feature allows users to view and control network resources conveniently and flexibly.

9) Support sparse files. A sparse file is a special type of file generated by an application that is very large in size, but actually requires very little disk space, that is, NTFS only needs to allocate disk storage space for the data actually written by such a file.

10) Support disk quota. Disk quotas manage and control the maximum disk space that can be used by each user.
