This article mainly explains "what are the advantages and disadvantages of changing u disk to ntfs format". the explanation in this article is simple and clear, easy to learn and understand. please follow the ideas of Xiaobian slowly and deeply to study and learn together "what are the advantages and disadvantages of changing u disk to ntfs format"!

The pros and cons of changing u disk to ntfs format are: NTFS is a recoverable, safe and efficient file system, designed to support multiple data streams, Western European character set names and bad cluster redirection; if the computer does not consider security issues, more attention to compatibility with Win 9X, then FAT32 format is the best choice.

Operating environment: Windows 7, Dell G3 PC.

The advantage of NTFS file system is that it has higher security than FAT32, and the advantage of FAT32 is that it is better compatible than NTFS. So which file system is more suitable for our use under the premise of satisfying the application? Let's first look at the characteristics of NTFS and FAT32 file systems.

NTFS & FAT32

NTFS file system

NTFS stands for "New Technology File System" and is a file system developed by Microsoft for Windows NT. It improves on the previous FAT file system and improves its performance. It is an advanced file system that is built on the basis of protecting files and directory data, while saving storage resources and reducing disk usage. Windows XP uses NTFS file system, which enables users not only to operate and manage computers as easily and quickly as Win 9X, but also to enjoy the system security brought by NTFS. NTFS supports NT*-based security management. Of course, there is no free lunch in the world, and extra space is needed when such management is needed. Generally, when running NT* as a system, it is best to vacate 10-15% of the hard disk space to ensure the normal operation of NT* as a system.

The NTFS file system has the following characteristics:

NTFS can support partition sizes up to 2TB (2048GB), while FAT32 supports partition sizes up to 32GB.

2. NTFS uses smaller cluster groups to manage disk space more efficiently. NTFS file system, when the partition size is less than 2GB, the cluster size is smaller than the corresponding FAT32 cluster, when the partition size is more than 2GB, the cluster size is 4KB. In the case of the FAT32 file system, the cluster size is 4 KB for partition sizes of 2 GB to 8GB, 8KB for partition sizes of 8GB to 16GB, and 16KB for partition sizes of 16GB to 32GB. NTFS, by contrast, manages disk space more efficiently and minimizes disk space waste.

3. NTFS automatically fixes disk errors without displaying error messages. When Windows XP writes a file to an NTFS partition, it keeps a copy of the file and checks that the file written to disk matches the file in memory. If the two do not agree, Windows marks the sector as bad and does not use it anymore (cluster remapping), and then writes the file back to disk using the copy of the file that is still in memory. If an error occurs while reading a file, NTFS returns a read error message and informs the corresponding application that the data has been lost.

NTFS has many security options to protect files and directories locally and remotely. NTFS also supports the Encrypted File System (EFS), which prevents unauthorized users from accessing files.

5. Another benefit of NTFS file systems is support for file compression, where users can choose to compress individual files or entire folders. Any Windows-based application that reads or writes compressed files on NTFS partitions does not need to be decompressed by other programs in advance. When the file is read, the file will be decompressed automatically; when the file is closed or saved, the file will be compressed automatically.

6. Disk quotas allow system administrators to manage disk space allocated to individual users, and legitimate users can only access their own files. Disk quotas in Windows 2000 are based on users and volumes.

FAT32 file system

Before the FAT32 file system, the file system commonly used by PCs was FAT16. Systems such as MS-DOS and Windows 95 use FAT16 file system. Under Win 9X, FAT16 supports a maximum partition size of 2GB. In the case of FAT16, the larger the cluster, the lower the storage efficiency, resulting in a waste of storage space. In this case, the enhanced file system FAT32 was introduced. FAT32 uses 32 bits of space to represent each sector profile. The use of FAT32 can be used by a single partition, up to 2TB (2048GB), and various sizes of partitions can be used by the size of the cluster, is also appropriate, the above two advantages, resulting in a more efficient use of the hard disk.

Compared with FAT16, FAT32 has the following characteristics:

1. FAT32 can support disk sizes up to 2TB and Windows XP can support partitions up to 32GB. FAT16 only supports 4GB partitions.

2. Because of the smaller clusters used, FAT32 file systems can save information more efficiently, usually by 15%.

III. Ending

NTFS differs from FAT in that it is not only a recoverable, secure and efficient file system, but is also designed to support multiple data streams, Western European character set names and bad cluster redirection. Multistreaming makes it possible to add new attributes or information to a file without having to rebuild the file system. The Western European character set can support any language in the world, and we know that ASCII code is only 7 bits, and the supported language type is English. Finally, the redirection of bad clusters enables NTFS to identify bad clusters, so that data written to them is not written to them, ensuring data security.

If you are using partitions larger than 32GB in Windows XP, the only option is NTFS format. If your computer doesn't care about security and is more concerned about compatibility with Win 9X, then FAT32 format is the best choice. If you pay attention to computer system security, it is recommended that users use NTFS format. If you want to use multiple * operating systems, you need to install Win 9X or other * operating systems. It is recommended that you make a multi-boot system, one partition in FAT32 format, the other partition in NTFS format, and Windows XP installed in NTFS format partition, other * operating systems installed in FAT32 format.

Thank you for reading, the above is "u disk to ntfs format advantages and disadvantages of what is the content, after the study of this article, I believe that we have u disk to ntfs format advantages and disadvantages of what this problem has a deeper understanding, the specific use of the situation also needs to be verified by practice.
