| 摘 要： | 针对一些有关NTFS文件系统的书籍和杂志中认为NTFS文件系统对索引目录的管理是采用B+树结构，通过对NTFS文件系统元文件$MFT文件夹记录的90H属性、A0H属性和B0H属性以及索引结点结构的分析，以实验的方式对索引文件进行查找、删除和插入运算来观察NTFS索引目录结构变化. 实验结果表明：NTFS文件系统对索引目录的管理是采用B-树结构，但并非是一棵标准的B-树.

| Abstract: | Aiming at managing the index directories in the NTFS file system, it uses B+ tree in some of books and magazines of NTFS, analyzes the 90H attribute, A0H attribute, B0H attribute in the folder recorder in the metafile $MFT and the structure of the index node in NTFS file system, observes to change the index directions in the NTFS by researching, deleting, inserting the file name in it by the mode of experiment. The experiment results indicate that the structure of the index directories in NTFS uses B-tree structure, but it isn''t the standard B-tree structure. |
