What is the difference between FAT32 and NATS partition

FAT supports up to 2 GB partition capacity. If the partition capacity exceeds 2 GB, you must format it by NTFS or split it into multiple smaller partitions. It should be noted that NTFS itself requires more resources than FAT.

The difference between ntfs and fat32 is that they support different partition sizes and different disk space utilization. Support different partition sizes. The main application scenarios of NTFS include computer disks and mobile hard disks.The disk partition in this format can reach 2TB and is mostly used to store large files.

NTFS partition is a newer partition format than the FAT32 version, so the NTFS format partition has more powerful functions than the FA32 partition, such as dividing each disk into larger space and having higher security attributes.

What is the difference between FAT32 and NEFS file system? What occasions are applicable to each?

1. Compared with NTFS, exFAT can support more devices and operating systems; it is larger than the single file supported by FAT32, with a maximum support of 1EB for a single file. ( 1EB=1073741824 GB) is very suitable for storing large files, and can also be used on Mac and Win operating systems.

2. A file system derived from the file allocation table (FAT) file system. Compared with FAT, FAT32 can support smaller clusters and larger capacity, thus allocating disk space more efficiently on FAT32 volumes.

3. FAT32 and NTFS are all types of hard disk partition format.FAT32 FAT32 refers to the file allocation table, which is a disk file management method that adopts 32-bit binary record management. Because the core of the FAT file system is the file allocation table, the name is derived from which FAT32 can only support 32GB partitions, and a single file can only support up to 4GB.

4. The difference between FAT32 and NTFS: What is NTFS-New (N) Technology (T) File (F) System (S)? If we want to know about NTFS, we should first know FAT. FAT (File Allocation Table) means "file allocation table". For us, its significance lies in the management of hard disk partitions.

What is the difference between FAT and FAT32 file systems? Which one is better? What's good about it?

The maximum number of files in the same directory of FAT is 512. The maximum number of files in the same directory of FAT32 is 65535. The maximum number of files in the same directory of exFAT is 18446744073709551615.

The FAT file system was not complicated considering the limited performance of the computer at that time, so it was supported by almost all personal computer operating systems. This feature makes it an ideal floppy disk and memory card file system, and is also suitable for data exchange in different operating systems. Now, FAT generally refers to FAT32.

Due to the use of smaller clusters, the FAT32 file system can save information more efficiently.For example, the size of both partitions is 2GB. One partition adopts the FAT16 file system and the other partition adopts the FAT32 file system. The cluster size of the partition using FAT16 is 32KB, while the cluster of the FAT32 partition is only 4KB.

In this case, the enhanced file system FAT32 was launched. Compared with FAT16, FAT32 mainly has the following characteristics: Compared with FAT16, the biggest advantage of FAT32 is that it can support a disk size of 2TB (2047GB), but it cannot support partitions smaller than 512MB.

Introduction to the principle of Fat file system

FAT is a file configuration table (EnglishLanguage: File Allocation Table, acronym: FAT), is a file system invented by Microsoft and has some patents for MS-DOS use, and it is also a file system used by all non-NT core Microsoft windows.

Formatting the file system is actually the process of writing some initialized metadata. The figure above is a complete FAT32 partition: FAT1: file allocation table, describing the cluster link relationship of file storage space (which cluster is the next cluster data stored in, because the cluster number of the data in the same file is continuous). FAT2: Backup of FAT1.

FAT does not refer to format, FAT is the file configuration table (full name is File AllocationTable) is a file system invented by Microsoft and has some patents for MS-DOS use, and it is also a file system used by all non-NT core Microsoft windows. A FAT file system consists of four different parts.

Due to the use of smaller clusters, the FAT32 file system can save information more efficiently. For example, the size of both partitions is 2GB, one partition adopts the FAT16 file system, and the other partition adopts the FAT32 file system. The cluster size of the partition using FAT16 is 32KB, while the cluster of the FAT32 partition is only 4KB.

The so-called file system is the way the operating system manages files. FAT is actually the abbreviation of the file allocation table, that is, the method of using the file allocation table to register files.

File allocation table: The contents of files and folders are stored in clusters. If a file or folder needs more than one cluster space, use the FAT table to describe how to find another cluster. The FAT structure is used to indicate the next cluster of the file and also to explain the allocation status of the cluster.

What are the common file systems?

There are four common file systems: FAT1FAT3NTFS and ExFAT. Although the storage methods and characteristics of the four file systems are different, for memory cards and USB flash drives with low transmission speeds, the actual transmission performance is similar. The theoretical test data is only 1MB/s different, and there may be differences in long-term use.

FAT1FAT3NTFS is the three most common file systems at present.FAT16: The DOS and Windows 95 we used to use the FAT16 file system, and now the commonly used Windows 98/2000/XP and other systems support the FAT16 file system.

The file systems we commonly use in Linux are mainly extext2 and reiserfs. The Linux operating system uses the virtual file system (VFS) up and user process files to access the system call interface, down and the implementation interface of different file systems. VFS shields the implementation details of specific files and provides a unified operation interface.
