NTFS is an acronym for New Technology File System. NTFS was first released with Windows NT. It is much more modern, stable and reliable than FAT or FAT 32. This file system was designed for use specifically with Windows OS. It supports long file names, huge disk partitions and files, full security access control, the ability to recover files/directories and its structure in the event of hardware failure and many other features.
Yes. The NTFS File System is replacement for the FAT (File Allocation Table) and HPFS (High-Performance File System) file systems. It gives many advantages over the other file systems such as the ability to restore files/directories and its structure in the event of hardware failure, improved security, supporting huge files/partitions and etc.
1.3 Is NTFS File System the same in every version of Windows?
There are three versions of NTFS File System: 1.2, 3.0 and 3.1. Each of these versions is used in different Windows OS and has additional features. NTFS version: v1.2; v3.0; v3.1 and accordingly - Windows version: NT 4.0, 2000, XP, 2003, Vista, 7, 8.1. Note: The version 1.2 is also known as 4.0, the versions 3.0 as 5.0 and the version 3.1 as 5.1.
You can convert FAT or FAT 32 volumes to NTFS ones by means of standard Windows applications. Click on Start and then on Run. In the command prompt window, type: convert : /fs:ntfs For example, type convert D: /fs:ntfs to format the D drive with the ntfs format. Note: Windows does not provide for conversion from NTFS to FAT. Use Partition Manager or Hard Disk Manager to convert FAT volumes to NTFS ones or vice versa.
Prior to Windows 7, Windows did not provide any built-in capable tool to resize NTFS volumes (in Windows XP and older versions there is even no function to resize NTFS volumes). To resize an NTFS volume you can use either Partition Manager or Hard Disk Manager, in particular their Recovery CD. Moreover, we have developed an additional utility using our UFSD SDK to resize NTFS partition under Linux.
Hierarchical File System (HFS) is a file system developed by Apple Inc. for use in computer systems running Mac OS. Originally designed for use on floppy and hard disks, it can also be found on read-only media such as CD-ROMs. HFS is also referred to as Mac OS Standard (or "HFS Standard"), where its successor, HFS Plus, is also called Mac OS Extended (or “HFS Extended”). With the introduction of OS X 10.6, Apple has dropped support to format or write HFS disks and images, which are only supported as read-only volumes.
HFS Plus is an improved version of HFS, supporting much larger files (block addresses are 32-bit length instead of 16-bit), using Unicode (instead of Mac OS Roman or any of several other character sets) for naming the items (files, folders), also uses a full 32-bit allocation mapping table so that disk could support more than 65,536 allocation blocks.
UFSD (Universal File System Drivers) is a unique technology specially developed by Paragon Software Group to provide full access (read/write, format, etc.) to volumes of the popular file systems such as NTFS, FAT, Ext2Fs, etc. under various platforms Windows, Linux, etc. in case these file systems are not natively supported.
4.3 The NTFS file system is proprietary technology of Microsoft. Is the NTFS for Linux driver absolutely legal?
It is well known that originally NTFS was very close to the HPFS file system developed by IBM. HPFS was much more OPEN in terms of documentation support, data structure and so on. It helped us to gain a better understanding of its nature, architecture and ideology. The knowledge about NTFS we also have got has already been used for years inside our best-seller product - Paragon Partition Manager. We have sold several million copies of Paragon Partition Manager all over the world. The stability of the products as far as NTFS related operations are concerned says for itself about the stability of the NTFS technology at all. Thus, having a pretty good idea about what the HPFS file system is, we may understand the way NTFS functions. Applying to the other sources of information like Linux drivers for NTFS (read only drivers) and debugging Windows applications, we've documented NTFS structures from within and finally created the Universal File System Driver. While developing Paragon NTFS for Linux driver we always stuck to the following rules:
We never referred to any confidential Microsoft NTFS stuff (docs, codes, etc.) and never applied reverse engineering approach for Microsoft’s binary code.
Open sources are the only thing we used. E.g. from www.ntfs.com we got the great part of our NTFS knowledge and understanding.
NTFS as a file system as well as on-disk layout is not patented and not documented.
UFSD provides access directly to the physical devices that is why it can process partitions regardless of their support by the current OS. With UFSD it is possible to mount NTFS partitions under Linux, thus getting access to its contents, just the way it is realized in the NTFS for Linux driver, and it also allows direct access via physical device addressing, the way it is realized in UFSD SDK.
Paragon NTFS&HFS for Linux software provides access to NTFS and HFS+ volumes under Linux. Now everyone can access NTFS and HFS+ partitions under Linux in a usual manner. The driver allows mounting NTFS or HFS+ partitions, so that programs can work transparently with these mounted partitions - browse contents, open documents, run applications, work with existing files and create new ones. The NTFS&HFS for Linux driver is a commercial Linux kernel driver for local access to NTFS or HFS+ volumes. It supports full read/write access. Kernel driver means you will have rapid and transparent access like to native file systems. Just mount manually or use automounting feature of the Professional version, and NTFS or HFS+ volumes will be available like any other tree directory.
Currently, the product supports Linux Kernels from 2.6.36 (on 2.6 Kernel branch), as well as up to 3.14.x (on 3.x Kernel branch). To keep up with the changes in Linux Kernel, our product is also updated frequently. Thus, this web site may not contain the most up-to-date information. Please contact our OEM licensing team at email@example.com to get the most up-to-date list of supported Linux Kernels. Additional porting activities may be required before the driver can be used on platforms with highly customized Kernels.
6.2 What performance is available for the NTFS access?
The NTFS&HFS for Linux performance is similar to the native NTFS performance and in some cases even better than performance of native Linux file systemsExt2 Data thoughput depends on CPU performance, cache performance (availability of RAM), the flow actual scenario of data writing (size of chunks and order of write operations), number of files written simultaneously, etc. However the major factor is the fragmentation of NTFS volume and files. In case of huge fragmentation performance could drop down significantly, compared to performance on non-fragmented files. Also, regardless of the summary data flow, performance for several simultaneous copy processes is 4-5 times slowly, but it is normal behavior, easily found on any other file system and operating sytem. For most popular embedded platforms, reference performance data can be provided by request (you can contact us at firstname.lastname@example.org).
7.1 Development Environment to install NTFS&HFS for Linux software
A development environment is required to compile Linux drivers and utilities. Please verify these tools are all functional. The easiest way is to choose the developer toolkit when installing Linux. What must be installed:
kernel source code (recommended) or header files (doesn’t always work) for the kernel;
#rpm -qa | grep kernel-devel (for RPM based kernel-sources)
GNU C (gcc) compiler (version 3.3 or higher is required);
7.2 Can I install NTFS&HFS for Linux software to Knoppix?
Yes, you can. To install the software you should have the kernel sources for the Knoppix on which you want to install the drivers and utilities. Usually, you can find the kernel sources for the Knoppix on its DVD version (not CD).
8.2 Can I mount NTFS/HFS+ volumes with non-english filenames?
If a partition to be mounted contains files or directories which names have non-English characters, please use the -nls option: "mount -t ufsd /dev/ /mnt/ -o nls= ". For example, "mount -t ufsd /dev/sda2 /mnt/ntfs -o nls=utf8" (run in a Linux console as root or place it into the /etc/fstab file).
8.5 Can I change the permissions of a mounted NTFS volume?
Since there is no way to map Windows accounts into Linux users, permissions for files and directories are set when a NTFS partition is mounted (similar to the FAT file system, which do not store any information about access rights at all). These permissions are controlled by the following mount options:
This behavior is different in Embedded and Desktop Products – see Implementation Gude or User manual respectively.
You can enable automatic mounting of NTFS/HFS+ volumes by adding lines to /etc/fstab (filesystem table) file or use the Paragon NTFS&HFS for Linux Professional version, which will add settings for automounting of NTFS/HFS+ volumes with the UFSD driver into your Linux system during installation.
9.1 Can I customize NTFS&HFS for Linux for non-standard hardware platform?
The architecture of the NTFS for Linux driver allows porting it to any hardware platform present on the present-day market. Paragon Software Group has a unique experience in customizing the NTFS for Linux driver for various platforms.
