1. What is NTFS-New (N) technology (T) file (F) system (S )?

To learn about NTFS, we should first understand 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 currently the most common three file systems. FAT16: the previously used DOS and Windows 95 all use FAT16 file systems, currently, common Windows 98/2000/XP and other systems support FAT16 file systems. It can manage up to 2 GB of partitions, but each partition can have up to 65525 clusters (the cluster is the disk space configuration unit ). As the disk or partition capacity increases, the space occupied by each cluster will become larger and larger, leading to a waste of hard disk space. FAT32: with the emergence of large-capacity hard disks, FAT32 has become popular since Windows 98. It is an enhanced version of FAT16 and can support up to 2 TB (20 48 gb partition. FAT32 clusters are smaller than FAT16, which effectively saves hard disk space.
NTFS: A series of operating systems supported by Microsoft Windows NT kernel, a disk format specially designed for management security features such as network and disk quotas and file encryption. With the popularity of Windows 2000/XP with NT as the kernel, many individual users began to use NTFS. NTFS also stores data files in units of clusters, but the size of the NTFS clusters does not depend on the size of disks or partitions. The reduction of the cluster size not only reduces the waste of disk space, but also reduces the possibility of generating disk fragments. NTFS supports file encryption management to provide users with high-level security assurance.

2. What systems can support the NTFS file system?

Only Windows NT/2000/XP can recognize NTFS systems. Windows 9x/Me, DOS, and other operating systems cannot support or recognize NTFS-format disks. Because the DOS system does not support the NTFS system, it is best not to make the C: disk as the NTFS system, so that it is easy to fix it in the DOS system after the system crashes.
NTFS and operating system support:
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?

Windows 2000/XP is backward compatible with the file system. It supports FAT16/FAT32 and NTFS, and NTFS is a dedicated format for Windows NT/2000/XP, it makes full and effective use of disk space, supports file-level compression, and provides better file security. If you only install Windows 2000/XP, we recommend that you select the NTFS file system. If multiple boot systems are used, the system disk (disk C) must be FAT16 or FAT32. Otherwise, multiple boot is not supported. Of course, the file system of other partitions can be NTFS.

4. How do I convert a FAT partition to NTFS?

For Windows 2000/XP, the partition format conversion tool "“convert.exe" is provided ". Convert.exe is a DOS command line program attached to Windows 2000. It can be used to convert FAT to NTFS without damaging the FAT file system. It is easy to use. First, switch to the doscommand line window in Windows 2000, and type: D: \> drive letter/FS: NTFS to be converted in the prompt. For example, if the system edisk is originally FAT16/32 and needs to be converted to NTFS, the following format can be used: D: \> convert e:/FS: NTFS. All conversions will be completed after the system restarts. I strongly recommend using this method for conversion!

In addition, you can also use specialized conversion tools, such as the well-known Powerquest Partition Magic 7.0, the software download page is http://soft.km169.net/soft/html/1964.htm. it is also very easy to use. Select the partition to be converted from the disk partition list on the page. Select the "Convert Partition" button from the interface button bar, or select the "Convert" command from the "Operations" drop-down menu of the interface menu bar. Activate this function. Select "NTFS" as the conversion output on the interface, and click "OK" to return to the main interface of the program. Click "Apply" in the lower-right corner of the page to add settings. After that, the system restarts and completes the partition format conversion.
5. How can I retrieve accidentally deleted files in NTFS format partitions?
You can use specialized software such as Final Data for NTFS or Get Data Back for NTFS 1.04. The files of the two software have good recovery results. I recommend that you use the powerful Data recovery function and fast Get Data Back for FAT 1.05/NTFS 1.04 (2 software), http://download-tipp.de/cgi-bin/suc...phrase&bool=and. If no file operation is performed after the file is deleted, the recovery rate is close to 100%. Therefore, do not wait until the file is deleted to install the software. It is best to install the software together with the Windows system and immediately restore the deleted file after it is deleted by mistake. Generally, the deleted file can be restored.

6. If Windows 2000/XP is installed on a drive C (NTFS format) and Windows cannot enter the drive C when it crashes in the DOS state, what should I do?

You can use the Windows 2000/XP installation disc to start to repair Windows, or create a Windows 2000/XP installation and startup emergency drive. Note: The installation program for Windows 2000 is on the installation disc of the program, while the emergency drive for Windows XP is provided independently and needs to be downloaded from Microsoft's website.

7. Can Final Data for NTFS or Get Data Back for NTFS be used to fix accidentally formatted hard disks?
Both software can restore the formatted and deleted data (except for low-level formatting ). Regular formatting only deletes data information, while low-level formatting deletes all data areas. When hard disk technology is not as advanced as it is now, the disk surface is easily worn out. Hard Disk users often use low-level formatting for frequent read errors. To fix a formatted hard disk, you can only remove it, install it on another computer, and then perform file repair. Final Data can even repair hard disks damaged by CIH viruses.

8. How can I directly read and write the NTFS file system in Windows 98 (FAT System?

When Windows 98 and Windows 2000/XP operating systems are installed on the computer, how can I directly read and write the NTFS file system under the FAT system? Although the FAT system can be converted to the NTFS system, sometimes we need to install Windows 98 and Windows 2000/XP at the same time on the machine. Now the trouble is coming. Since Windows 98 cannot read the NTFS of Windows 2000, how can we exchange data? In fact, we only need to use a small software NTFS for Windows 98 to make Windows 98 easy to read and even write into NTFS partitions. First, go to the tool download URL asp? Id = 514 "> http://down.hothost.com/list.asp? Id = 514 download NTFS for Windows 98 1.07 (read and write !). After decompression, put the entire CR directory (there are 7 system files that must be used to read the NTFS file system to Windows 2000/XP, And the other 3 are comment files) COPY to drive C (you can also change the name to NTFS_FILES, Which is changed in this way). After the installation is complete, a configuration interface will appear, in the "NTFS System Files" item on this interface, you need to set the storage path for the Files of Windows 2000/XP that can be borrowed by the program, select COPY to the CR directory of the disk, and you do not need to perform any other operations. The settings are complete. Click OK to save the settings and exit. After restarting, you can access the NTFS partition under Windows 98! After actual use, it is proved that the software can be read and written on the NTFS partition after being installed!
The above content is verified on WIN98SE + WINXP_PROCN + WINXP_PROEN and WINME + WINXP_PROCN + WINXP_PROEN! (2 machines)

The following content is for reference only. We recommend that you do not implement it. At least I did this.
The [Drive Letter Assignments "item sets the NTFS partition Drive letters that can be recognized. For details about the settings, refer to the Drive Letter sequence in Windows 2000/XP. If you click the "Advanced" button on the page, the Advanced settings for the Set NTFS partition are provided in the association interface, this includes setting the Read-Only attribute and allowing Write-Through ". For the Checkpoint Interval "Checkpoint Interval" and the write-back Interval "Writeback nterval", use the default settings provided by the program.]

9. How can I directly read and write the NTFS file system in the DOS system?

Winternals Software LP provides tool Software to solve this problem. With a MS-DOS boot disk can do previously impossible to do, modify, delete, update NTFS files, the actual NTFSDOS pro is a repair tool in Windows NT problems.

10. In the NTFS system, how do I protect my files and folders?

Because 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 very effective. Easy Setup: Log On As a system administrator, right-click the folder to be encrypted, select Properties, and switch to the Security tab. Set "Group of user names" to allow only the Administrator and the user. Delete all other users. Save the settings and exit. After that, other users will not be able to access this folder. When using this function, you must ensure that only one of you knows the Administrator password and that other users cannot belong to the Administrator. In addition, you can set detailed permissions for each user, including the read permission, write permission, and delete permission, so that they can be used more flexibly. You can also set permissions to control a disk, or the disk partition is only for your own use, so that others will not be able to see anything about you.
