The final program was NTFSDOS Professional - a whole commercial solution for handling read and write operations in NTFS from a DOS environment. It must be installed as a package for Microsoft Windows first. The downloaded version comes in demoware form. The user can only use the package in read-only mode in order to evaluate it.
In NTFS, all file, directory and metafile data—file name, creation date, access permissions (by the use of access control lists), and size—are stored as metadata in the Master File Table (MFT). This abstract approach allowed easy addition of file system features during Windows NT's development—an example is the addition of fields for ...
VFAT, a variant of FAT with an extended directory format, was introduced in Windows 95 and Windows NT 3.5. It allowed mixed-case Unicode long filenames (LFNs) in addition to classic 8.3 names by using multiple 32-byte directory entry records for long filenames (in such a way that old 8.3 system software will only recognize one as the valid directory entry).

A typical new file creation event on an NTFS volume, then, simply involves NTFS allocating and creating one new MFT record, for storing the new file entity's file metadata—including, about any of the data clusters assigned to the file, and the file's data streams; one MFT record for a hard link which points to the first newly-created MFT ...
For backwards-compatibility with MS-DOS and older Windows software, which recognizes filenames of a maximum of 11 characters in length with 8.3 format (i.e.: an eight-letter filename, a dot and a three-letter extension, such as autoexec.bat), files with LFNs get stored on disk in 8.3 format (longfilename.txt becoming longfi~1.txt), with the ...
In computing, format is a command-line utility that carries out disk formatting. It is a component of various operating systems, including 86-DOS, MS-DOS, IBM PC DOS and OS/2, Microsoft Windows and ReactOS.
