Free ntfs software for windows

Ever wondered why you cant put NTFS on a floppy disk? Windows NT has never supported NTFS floppy disks, because Microsoft claims that floppy disks are too small for NTFS data structures. NTFSFlp is an application that will both format and enable NTFS support on floppy disks and proves this to be wrong. Now you can see for yourself why NTFS on floppies, while possible, is not a great idea.
Note: NTFSFlp should be run before you access your floppy drive for the first time after a reboot of your machine. If you mount a FAT drive and then run NTFSFlp, the FAT file system driver will crash the machine when the characteristics of the floppy drive change out from under it (see How It Works, below, for more information).
The first thing you will want to do is to format an NTFS floppy. Insert a floppy into your a: drive and enter "ntfsflp /f". Once the format is complete you will be able to access and write to the NTFS floppy in the same way as FAT floppies. You will notice is that there is significantly more disk activity, even when simple operations are performed, on the NTFS floppy than would occur on a FAT floppy. In addition, disk activity will continue for some time after you perform a modification of the data on the floppy. For this reason, I have included ntsync in this package, so that you can flush data onto an NTFS floppy before removing it.
NTFS floppy support must be enabled with NTFSFlp before you can access an NTFS floppy disk. Support is automatically enabled when you format an NTFS floppy, but can also be enabled by running NTFSFlp and not specifying any command-line arguments. You would need to do this if you created an NTFS floppy disk, rebooted the system and wished to access the floppy again.
NTFSFlp is a demonstration of NTFS floppy-disk support. It is not envisioned that anyone would want automatic NTFS floppy-disk support every time you run NT, so NTFSFlp must be used to manually enable support.
Windows NT actually goes to some lengths to prevent a user from creating an NTFS floppy disk. The first line of prevention is in the format utility. If a user specifies an NTFS format, format checks to make sure that the media is not a floppy. Then it checks to see if the medium is large enough to fit "minimum" NTFS on-disk data structures. Finally, it attempts to make an NTFS log file that is 2MB in size - an operation that will obviously fail on a 1.44MB floppy.
If you manage to get past these hurdles and get NTFS on a floppy, the NTFS driver itself will fail to mount floppy disks. Further, NTFS requires that the device driver for the media it is mounting implement the IOCTL_DISK_GET_PARTITION_INFO device I/O control call, something that floppy disk drivers are not required to do (and generally dont).
Using SoftICE for Windows NT I was able to trick format into creating an NTFS floppy disk with a log file that is only 256KB in size. This is large enough for NTFS to be able to function, and leaves 1MB of space on the floppy after NTFS structures have been created. To format an NTFS floppy, NTFSFlp copies the image of the NTFS floppy I created onto other floppy disks.
To trick NTFS into mounting an NTFS floppy, NTFSFlp loads a device driver, flpflt.sys, that changes the characteristics of the floppy disk device so that it does not look like a floppy. Flpflt also intercepts Device I/O Control calls that are directed at the floppy and implements IOCTL_DISK_GET_PARTITION_INFO. Note that flpflt.sys is not a filter driver - it reaches into the floppy0 device object and changes its characteristics, and replaces the IRP_MJ_DEVICE_CONTROL vector in the floppy drivers request handler table to point at its own. This technique is an example of another way to intercept and control requests that are sent to a device, and is in many senses actually more powerful than filtering in the traditional NTFilemon way.
NTFS floppy disks could be useful for storing compressed files on a floppy. In addition, NT 5.0 NTFS supports encryption, which would make it possible to have secure floppy disks.

NTFS Reader 2.1 is known as a free, yet very useful tool that provides a read access to NTFS disks from Windows 95, 98 and Me. It is designed to save any files from NTFS disks to any visible local or network drive. Compressed and encrypted files are supported. With NTFS Reader, you can easily get access to documents saved in Windows 2000, XP from Windows 9x. Read our Step by step Tutorial for a more detailed description of working with the program.

Spiff NTFS Explorer 1.0 is a helpful program to explore NTFS file system directly without going through the operating system. Shows all files, even those that are used by the file system itself. Inspect file system records and see all details including physical sector locations. .NET dll available for including functionality in your own applications. Undelete files, it does not matter if the deleted files were deleted through the recycle bin or not. Searching for deleted files is fast, the master file table records are searched, it does not take hours like some other products that scan the entire drive.

As you know length of path in NTFS file system may reach 32767 characters but most of functions in Windows API permit a maximum path length 260 characters. The LibMaster.com NTFSpath library allows to work with a maximum path length 32,767 characters which is allowed in NTFS. It contains most useful functions for working with path strings and NTFS file system. Both of separators "/" and "\" are equivalent for all of the functions in the library. Also no one of the functions do not trim spaces before the begin and after the end of an input string because NTFS allows space characters at the begin and at the end of filename or directory name.
The archive with the library has an application with examples of using for the all functions in the library.

You can use this library for free.
