It's been half a year.,Landlord,FAT32The format can't put more than 4G single files.,For example, the cartoon "Food Story" has.

You are only in. NTFS area.

FAT32 partitions can only support a maximum of 32GB partitions, and a single file can only support a maximum of 4GB.

FAT32 is developed from FAT and FAT16, which has the advantage of good stability and compatibility, can be fully compatible with WIN 9X and earlier versions, and is easy to maintain. The disadvantage is poor security.

The FAT32 file system consists of DBR and reserved sectors, FAT1, FAT2 and data zones

1. DBR and reserved sectors: DBR means DOS boot record, also known as operating system boot record, and there are often some reserved sectors after DBR.

2. FAT1: The meaning of FAT is the document allocation table, FAT32 generally has two copies of FAT, FAT1 is the first and main FAT.

3. FAT2: FAT2 is the second file allocation table of FAT32 and a backup of FAT1.

4. data: data is the data area, which is the main area of the FAT32 file system, including the directory area.

Win 2000 based on FAT32 can support partitions up to 32GB; The biggest advantage of the partition supported by FAT 16 is that it can support a disk size of up to 2TB (2047GB), but it cannot support partitions smaller than 512MB.

Thanks to the smaller clusters, the FAT32 file system can store information more efficiently. For example, if the size of two partitions is 2GB, one partition uses the FAT16 file system and the other partition uses the FAT32 file system. The cluster size of the FAT16 partition is 32 KB, while the cluster of the FAT32 partition is only 4 KB in size.

In this way, the storage efficiency of FAT32 is much higher than that of FAT16, which can usually be increased by 15%.

Features of FAT32:

1) The FAT32 file system still divides the space of the logical disk into three parts, which are the boot area, the file allocation table area, and the data area. The bootstrap area and the file assignment table area are collectively referred to as the system area.

2) The structure of the MBR and extended partitions of FAT32 is still the same as that of DOS. It's just that the bootloader is different. In the previous section, MBR used the Win98 bootloader. I won't repeat it here.

3) The boot area of FAT32 starts from the first sector, uses three sectors, and saves the number of bytes per sector of the logical disk, the number of sectors corresponding to each cluster, and other important parameters and boot records. After that, a number of reserved sectors remained.

4) The structure of the file allocation table in FAT32 is the same as that of FAT16 under DOS, and the cluster chain structure is still used to manage files, but an entry in FAT32 uses 4byte or 32 bits, so that the file allocation table can have more clusters and can manage larger disk space.

The maximum partition capacity of FAT32 is 2TB.

Reason: According to the FAT32 file system, a 32-bit binary number is used to represent the cluster number, and each FAT file can manage 4294967296 clusters to the power of 32 of 2, and the capacity of each cluster is 512KB, so the maximum partition capacity can be calculated as 2TB. However, only FAT32 partitions with a maximum size of 32 GB can be managed under XP.

Basic Introduction: FAT32 is a type of hard disk partition format for Windows system. This format uses a 32-bit file allocation table, which greatly enhances its disk management capabilities, breaking through the FAT16 limit of only 2 GB per partition. Due to the decline in the production cost of hard disks and the increasing capacity of hard disks, after using the FAT32 partition format, we can define a large hard disk as a partition instead of dividing it into several partitions, which greatly facilitates the management of disks.

However, due to the fact that a single file larger than 4GB cannot be stored in the FAT32 partition and its performance is poor, disk fragmentation is likely to occur. It has been replaced by the more high-performance NTFS partition format.

1. First of all, select all the files that need to be backed up on the i disk, and right-click "Add to Compressed File".

2. Select the path and file name of the backup, and click "Compress Now" to back up the file.

3. After the file backup is completed, right-click on the "i drive" drive letter and select "Format".

4. In the "Format" window, select "NTFS" for the file system and click "Start" to format the disk.

5. After waiting for completion, the disk will become the NTFS file system, restore the backup file, and you can save more than 4G large files.

The 2TB limit is not a FAT32 file system, but is based on an MBR disk. On an MBR disk, the partition start offset is recorded in 4 bytes (and also the number of sectors in the partition), so when all 4 bytes of data are the maximum ff, the corresponding decimal is 4294967295 sectors.

Therefore, 4294967295 sector 512 bytes = 2199023255040 bytes = 2199GB = 2048 giB

In fact, there are workarounds to break this limitation, but it is not very common.

In addition, Windows requires that FAT32 volumes must contain at least 65,527 clusters, not 65,537 clusters.

ExFAT is generally used for quick plugging and unplugging USB flash drives and TF cards, and is not suitable for disks;

In FAT32, a single file cannot exceed 4GB, and NTFS is recommended for disks, and there are two ways to convert it.

1. Direct formatting.

2. Press win+r, enter cmd, enter the space in the command symbol and don't lose the even, and then press enter;

Then, right-click on the disk you want to change, rename it to pan, tips: must be in English!

In cmd, enter pan and press enter. (This will preserve the file).

And what is Exfat?

FAT32 is a type of partition format for hard disk in Windows system. This format uses a 32-bit file allocation table;

ExFAT (Extended File Allocation Table File System, also known as FAT64) is a file system suitable for flash memory introduced by Microsoft in Windows Embeded (including Windows CE Mobile).

2.About FAT32

The older version of FAT32 could not store a single file larger than 4GB and was prone to disk fragmentation due to its partitioning characteristics, so it has been replaced by the more powerful NTFS system. However, FAT32 can be directly accessed under the DOS system, while NTFS does not support direct access under the DOS system, please choose according to your needs. In fact, the conversion between FAT32 and NTFS only requires the hard drive to be formatted (which will result in the loss of data that has not been backed up to other media).

3.About ExFAT

ExFAT is actually a file system for flash memory devices (USB flash drive TF card), which is a compromise between FAT32 and NTFS, and is not suitable for use on hard disks. There is no obvious problem if you store large files on an ExFAT formatted hard drive, but if you store a large number of small files, you will have a very large space footprint. Due to partition problems, less than 400G of data (various files, movies, games, documents, program source files, etc.) is only occupied in NTFS, and moving to ExFAT may be 600G faster.

4.Select a file system based on your needs.

If you are just an ordinary Windows user, it is recommended to choose NTFS as the file system of the hard disk; If you are using a Linux system, you may also format it to ext3, rfs, and xfs file systems as needed. Your USB flash drive or portable hard drive can be formatted into FAT32, EXFAT or NTFS systems according to your needs.

I don't know if it's a grave dug ... Both. However, the main disadvantage of FAT32 is that the size of a single file cannot exceed and is mainly suitable for USB flash drives with a capacity greater than 4GB, and it seems that no one has done it on a hard disk.

You can try. I've tried ExFAT for sure both Mac and Windows can read and write. Because my USB flash drive is Exfat, ExFAT also has a single file size limit that is much larger than 4GB.

So I personally recommend using Exfat. Good luck with it!

FAT32 is already an old-fashioned format, disadvantages: you can't transfer files above 4G.

ExFAT is usually used as a flash drive format, and USB flash drives are currently the best option.

ExFAT is the most suitable file system for flash memory, which can balance high-capacity file storage, transfer performance, and longevity.

The maximum single file of FAT32 cannot exceed 4G, do you still want to format FAT32 when you see this?

ExFAT is actually FAT64, which is generally used for flash memory, and very few hard drives use this format Maybe the system doesn't support it, maybe there are other drawbacks.

Format: NTFS and FAT32 XP are commonly used, the default startup disk is FAT32, and the Vista and Win7 startup disks are by default.

Nifs is going to talk about the good and bad explanations, it's just a format, and some files need to be in what format disk to use.

Each has its own benefits. There are no drawbacks.

Take you to understand the difference between hard disk FAT32 and EXFAT, if you don't understand, you can take a look!

FAT32 does not support a single file size exceeding 3G, and it cannot be copied if it is exceeded

FAT32 files do not support a single file over 4G.

FAT32 format features: Create a single partition up to 32GB, which can be directly accessed under the DOS system, but it is compatible. It cannot store a single file larger than 4GB, which is prone to fragmentation, has poor security, and does not support long file names.

EXFat is the latest format for USB drives and portable hard disks, which is very similar to NTFS, and is characterized by high space utilization, good security, and good support for long file names. Compatibility could be improved.

Windows in both formats can access the Mac system, but the Mac cannot access the FAT32 format.

According to the description of the problem, it is recommended to set the partition format of the hard disk to NTFS format, and briefly explain the reason.

The FAT32 format is a partition structure proposed from Microsoft Windows 98 system, which can support a maximum partition capacity of 32G, but the disadvantage is that it does not support the storage of a single file of more than 4G.

The NTFS format can support partitions (called volumes if they are dynamic disks) up to 2TB in size.

The ExFAT format is a file system suitable for flash memory introduced by Microsoft in Windows Embeded above, and was introduced in order to solve the problem of FAT32 and other files that do not support 4G and larger.

Therefore, in view of the situation described in the problem, it is recommended to format the hard disk to NTFS format.
