advantages of NTFS

NTFS appeared in Windows NT for the first time. At that time, the mainstream file system for Windows was FAT32, but NTFS replaces FAT32 in a short time. Next, let me analyze advantages of NTFS compared with FAT32. 

Security: on NTFS partition, we can set access permission for shared resource, file folder, and file. In addition, the permission is not limited to user group, and it also works for network users. Besides, NTFS security logs record audit information for file folder, file or object in active catalogue. Through these records, we can view who operate file folder, file, or active catalogue object, finding illegal visit the system will face. Therefore, the security of NTFS is higher than that of FAT32. 

NTFS supports managing larger file: nowadays, large-capacity files emerge unceasingly, but the biggest file size FAT32 can support is 4GB. Obviously, FAT32 can not meet users' demands for current file management. 


Supports file compression: NTFS supports compression for file, partition and file folder. When we read compressed files, these files will be decompressed automatically. After we close these files or save them,
 they will be compressed automatically. But FAT32 does not have this function. 

 Reliability: NTFS is a recoverable file system, and it ensures partition consistency through standard transaction log and recovery technology. When system failure happens, NTFS automatically recovers file system consistency by using log files and checkpoint information, which can no be realized by FAT32. 

On account of the above reasons, NTFS replaces FAT32 quickly, and becomes the most commonly used Windows file system.
