The rookie tutorial on NTFS details

There are many proper nouns in the system, but many of these proper nouns seem to understand, such as NTFS. Although many readers know the term NTFS, the details are still confusing. For example, some people think that NTFS does not support the game well. Its security is reflected in the place, that is, it seems that there is no feeling of using it. This article will give you a satisfactory answer about NTFS.

First, what is the file system and NTFS

First of all, you need to clarify the reader's misunderstanding of the file system, often have this saying, "My hard drive is FAT32 format" , "C disk is NTFS format", etc., their mistake is that NTFS or FAT32 is not a format, but a system for managing files. Secondly, the hard disk that you just bought does not have a file system, you must use FDISK or windows 2000/XP partitioning tools, etc., will partition and format the system to manage files, so the file system is the corresponding partition, not the hard disk, whether it is divided into a partition, or several partitions.

For a common analogy, a hard disk is like a piece of open space, the file is like a different material, we must first build a warehouse (partition) on the open space, and specify the (format) warehouse material The management specification (file system) so that materials can be shipped to the warehouse for storage.

Files are not affected by the file system of the partition in which they are located, just as car tires may be stacked directly on the ground in the A warehouse, while the B warehouse is hung on the wall, just different in placement and management methods. Therefore, files on NTFS partitions and FAT32 partitions can be moved between partitions at will, and the content will not be any different.

The full English name of NTFS is "NT File System"; Chinese means NT file system (right click on "My Computer" in the "My Computer" folder, you can see it in the pop-up window. File system information). It was born with Windows NT 4.0 in July 1996, but it was not until Windows 2000 that it began to be promoted among individual users and entered the ranks of the main partition file system. Today, windows xp/2003 and NTFS have long been "like glue".

We know that the appearance of the FAT32 file system can be said to have a significant improvement for FAT16, but the improvement of FAT32 by NTFS must be described as "excellence".

The NTFS maximum partition limit has reached 2TB (1TB=1024GB). Since its birth, it has experienced multiple versions. The version in Windows NT4.0 is 1.2, Windows 2000 is 3.0, and Windows XP is 3.1. If you want to view the current NTFS version number, just type "lds;fsutil fsinfo ntfsinfo c:" in the command prompt (C is the partition drive letter).

Tips

Common File Systems

FAT12: is the file system used by MS-DOS 1.0 on IBM's first personal computer, mainly for floppy disks. This system limits the partition capacity to a maximum of 16MB & mdash; — but this is not a problem at all, because the floppy disk capacity never reaches 16MB.

FAT16: It is supported by many operating systems, and the compatibility is the best, but the partition can only be up to 2GB, and the space was wasted. And because the FAT16 file system is a single-user file system, it does not support any security and long file names.

FAT32: It is developed on the basis of FAT16. With the release of Windows 95 OSR2, it can be supported by most operating systems. FAT32 utilizes hard disk space more effectively than FAT16, and the maximum partition limit has been It has reached 32GB and is suitable for general household use.

ISO9660: CD-ROM file system, but now has extended a lot of new file systems, and made up for some of its shortcomings, such as Juliet.

UDF: A file system that can read and write optical discs.

Mac HFS: Apple's file system, which has good support for large-capacity disks. However, most Apple computers still use the FAT32 file system.
