NTFS下文件在$Bitmap的位置定位算法研究

Research of arithmetic the file in $ Bitmap's position in NTFS

通过对NTFS文件系统元文件$MFT和$Bitmap结构,以及文件的数据运行列表在元文件$MFT中存储形式的分析与研究,推导出了文件的簇号在元文件$Bitmap定位的基本算法,解决了在研究NTFS文件系统位图文件时,难以定位簇号在位图文件位置中的问题.

By analyzing the structure of the metafile $ MFT and $ Bitmap in NTFS file system,we research Files' data run lists of the metafile $ MFT and educe the basic arithmetic of the file clusters,and solve the problem that the file clusters' number was gone to the metafile position in the course of researching the metafile in NTFS file system.
