1. What is NTFS - New (N) Technology (T) File (F) System (S)?
To understand NTFS, we should first understand FAT. FAT (File Allocation Table) means "File Allocation Table". For us, its significance lies in the management of hard disk partitions. FAT16, FAT32, and NTFS are the three most common file systems currently.
FAT16: The DOS and Windows 95 we used before all used the FAT16 file system. Now commonly used Windows 98/2000/XP and other systems support the FAT16 file system. It can manage partitions up to 2GB, but each partition can only have up to 65525 clusters (clusters are the configuration units of disk space). As the hard disk or partition capacity increases, each cluster will occupy more and more space, resulting in a waste of hard disk space.
FAT32: With the emergence of large-capacity hard drives, starting from Windows 98, FAT32 became popular. It is an enhanced version of FAT16 and can support partitions up to 2TB (2048G). FAT32 uses smaller clusters than FAT16, thus effectively saving hard disk space.
NTFS: A series of operating systems based on Microsoft Windows NT kernel Supported, a disk format specially designed for management security features such as network and disk quotas, file encryption, etc. With the popularity of Windows 2000/XP with NT as the core, many individual users have begun to use NTFS as a cluster. To store data files, the size of the cluster in NTFS does not depend on the size of the disk or partition. The reduction of the cluster size not only reduces the waste of disk space, but also reduces the possibility of disk fragmentation. NTFS supports file encryption management functions. Provide users with a higher level of security.
2. What systems can support NTFS file system?
Only Windows NT/2000/XP can recognize NTFS system, Windows 9x/Me Operating systems such as DOS cannot support or recognize NTFS format disks. Since DOS systems do not support NTFS systems, it is best not to make the C: drive an NTFS system, so that it can be easily repaired under a DOS system after a system crash. p>
NTFS and operating system support are as follows:
FAT16 windows 95/98/me/nt/2000/xp unix, linux, dos
FAT32 windows 95/98 /me/2000/xp
NTFS windows nt/2000/xp
3. Do we need NTFS?
What is the file system of Windows 2000/XP? It is backward compatible and can well support FAT16/FAT32 and NTFS. NTFS is a special format for Windows NT/2000/XP. It can more fully and effectively utilize disk space, support file-level compression, and have better file security. If you only install Windows 2000/XP, it is recommended to choose the NTFS file system. If you use a multi-boot system, the system disk (C drive) must be FAT16 or FAT32, otherwise multi-boot is not supported. Of course, the file system of other partitions can be. NTFS.
4. How to convert FAT partition to NTFS?
Windows 2000/XP provides the partition format conversion tool "Convert.exe" included with Windows 2000. A DOS command line program, through this tool you can directly convert FAT to NTFS without damaging the FAT file system. Its usage is very simple. First, switch to the DOS command line window in the Windows 2000 environment, and type at the prompt: D:\>convert the drive letter to be converted /FS:NTFS.
If the system drive E was originally FAT16/32 and now needs to be converted to NTFS, you can use the following format: D:\>convert e: /FS:NTFS. All conversions will be completed after system restart. I recommend using this method for conversion!
In addition, you can also use specialized conversion tools, such as the famous hard disk lossless partition tool Powerquest Partition Magic 7.0. Download NTFS for Windows 98 version 1.07 (can Read and write!).
After decompression, please COPY the entire CR directory (there are 7 system files in Windows 2000/XP that must be used to read the NTFS file system, and the other 3 are annotation files) to the C drive (also It can be renamed NTFS_FILES, I changed it like this). After the installation is completed, a configuration interface will appear. In the "NTFS System Files" item in the interface, what needs to be set is the storage of relevant files in the Windows 2000/XP system that the program can borrow. Path, you just select the CR directory that you just copied to the disk, and then you don’t need to do anything else. The settings are now complete, click the OK button to save the settings and exit. After restarting, you can access the NTFS partition under Windows 98! After actual use, it is proved that after installing this software, it can read and write on the NTFS partition!
The above content has been verified by me on WIN98SE+WINXP_PROCN+WINXP_PROEN and WINME+WINXP_PROCN+WINXP_PROEN! (2 machines)
The following content is for reference only. It is recommended that you do not implement it, at least that is what I did.
The settings provided in the "Drive Letter Assignments" item are to set the NTFS partition drive letters that can be recognized. The basis for the settings can refer to the drive letter sequence under Windows 2000/XP. If you click the "Advanced" button in the interface, advanced settings for the NTFS partition are provided in the associated interface, including setting the read-only attribute "Read-Only" and allowing writing to "Write-Through". For the checkpoint interval "Checkpoint Interval" and writeback interval "Writeback interval", just use the default settings provided by the program.
9. How to directly read and write NTFS file system under DOS system?
Winternals Software LP company provides tool software to solve this problem. Using an MS-DOS boot disk, you can do things that were impossible before, such as modifying, deleting, and updating files on NTFS. In fact, NTFSDOS pro is a repair tool when Windows NT has problems. Download page/searchengine.asp, type "NTFS" to search for the site software, you can find NTFSDOS PRO 4.0, it is best to choose server 2 to download. The specific installation process is not complicated, just follow the prompts to prepare the boot disk.
10. How to protect your files and folders under the NTFS system?
Since the NTFS file partition format has good security, if you do not want your files on the hard disk to be called or viewed by others, using permission control encryption is a very effective method. The setting method is very simple: log in as the system administrator, right-click the folder that needs to be encrypted, select "Properties", and switch to the "Security" tab. In the "Group of user names" item, set the only users allowed to access are Administrator and yourself. Delete all other users. Save the settings and exit. Thereafter, other users will not be able to access the folder. Things to note when using this function: Make sure that only you know the Administrator password, and set other users so that they cannot belong to Administrator.
In addition, you can also set permissions for each user in detail, including setting read permissions, write permissions, delete permissions, etc., so that it is more flexible to use. You can also set permissions to control a disk or partition a disk just for yourself, so others can't see anything about you.
