FAT32与NTFS文件系统碎片提取研究

Research on Fragment Extraction of FAT32 and NTFS File System

在FAT32与NTFS文件系统中,文件通常是以簇为单位存储的,并且根据文件存储的先后顺序连续分配相应的簇。但在实际中,经常会出现文件删除或者替换等操作,这样就容易产生碎片,FAT32和NTFS因文件系统结构不一样,碎片文件的提取方法也不一样。碎片文件的存在容易影响系统的运行性能,降低文件读取速度和硬盘寿命,所以磁盘碎片整理是必要的。

In FAT32 and NTFS file systems,files are usually stored by clusters,and the corresponding clusters are continuously allocated according to the order of file storage.However,in practice,there are often operations such as file deletion or replacement,which will easily lead to fragmentation.Due to the different file system structures of FAT32 and NTFS,the extraction methods of fragmented files are also different.The existence of fragmented files is easy to affect the system performance,reduce the file reading speed and hard disk life,so disk defragmentation is necessary.
