In the Organization of files NTFS plays a fundamental role the main file (MTF) table, this table contains a record (record MTF) that in turn contains the file attributes for each file and the data on which parts of the file can be found in according to which clusters on your hard disk. There is a backup copy of the MFT that in case of hard disk failure can be used for its reconstruction and the MTF as your copy can be found anywhere on the hard disk since they are treated as what they are, completely normal NTFS file. The size of the MFT record is 2 KB and is composed of:-header (which contains internal system data of) files) – name and information of the file and its attributes. -Reference to the sectors where different parts of the file are located. -Advanced NTFS file system security attributes. In NTFS directories are treated as files as in most systems of single files in NTFS containing other attribute, therefore also a record exists in the MFT of directories or directory that is saved as a composite index for the name of the files and subdirectories and a unique file number. If the index occupies less than 1.44 KB being placed directly in the MFT for index files larger are saved as if they were files and directories big so there in the original MFT record only references to other MFT records are those that actually contain data.

I.e., for each directory we have a tree where hanging files and directories that contain. This is called binary tree and allows access to the data will be much faster, let us remember that in the FAT to search for a file You should first examine the table completely and also they are not sorted. FRAGMENTATION of the hard disk already have seen how hard disk stores data in sectors consecutively, the information about which parts of a file is found in which sectors it is stored in the mapping table file system NTFS is called Master File Table (MFT) when files are deleted, areas which are free can again be used although in theory can not be overwritten until all is not used of the disc.
