计算NTFS磁盘已用空间和自由空间的基本方法

A basic method for calculating diskette used space and free space for NTFS

  • 摘要: 作者使用Winhex磁盘编辑软件,分析NTFS文件系统元文件Boot的BPB参数以及BadClus和Bitmap结构,提出通过统计NTFS的位图文件中二进制数“1”的个数与“0”的个数来计算磁盘已用空间和自由空间的基本方法.

     

    Abstract: We used the Winhex editing software to analysised BPB parameter in the metafile Boot,the structure for BadClus and Bitmap in NTFS file system. We brought forward a basic method for calculating diskette used space and free space,which was totaling amount for binary digit “1” in bitmap file and binary digit “0” in Bitmap file in NTFS file system.
