Junction Link Magic (340 kB - Windows 2000/XP/2003/Vista/2008/Windows 7) is a utility that lets you create junction points with Windows 2000, XP, 2003, Vista, Windows Server 2008 and Windows 7. Acknowledgement: parts of the Junction Link Magic code are courtesy of: Note: if you just want to link a file instead of a folder, this is called a hard link . Take a look at Hermann Schinagl's free program Hard Link Shell Extension . A junction point is a special type of reparse point.

NTFS Master File Table
The NTFS file system contains at its core, a file called the master file table (MFT). There is at least one entry in the MFT for every file on an NTFS volume, including the MFT itself. Because utilities that defragment NTFS volumes cannot move MFT entries, and because excessive fragmentation of the MFT can impact performance, NTFS reserves space for the MFT in an effort to keep the MFT as contiguous as possible as it grows. A defrag operation on the MFT combines an MFT file into 1 and prevents it from being stored in multiple places that are not sequential on disk. In this class of operation, the MFT file is more sequential.NTFS is a high-performance and self-healing file system proprietary to Windows XP Vista 2003 2000 NT & Windows 7, which supports file-level security, compression and auditing. It also supports large volumes and powerful storage solution such as RAID.
NTFS General Information
Recovering NTFS Boot Sector
When a volume on a server or workstation becomes inaccessible or Disk Administrator shows it as "unknown", you may have a corrupt or damaged boot sector. This article will tell you how to find the second copy that NTFS stores and restore to the correct position on the disk. In order to resolve the problem, we need to retrieve the copy of the backup bootsector and copy it back to the correct position on the Hard Disk. In NT 3.5x, the second copy is kept in the center of the logical volume (Volume middle). In NT 4.0 and Windows 2000, it has been moved to the end of the logical volume (Volume end), which requires a different retrieval technique. The example shown will be using Disk Probe (dskprobe.exe) for NT which ships on the NT V4.0 Resource Kit but will also run under NT V3.5x with the proper .dll files installed.
All file systems used by Windows organize your hard disk based on cluster (or allocation unit) size, which represents the smallest amount of disk space which can be allocated to hold a file. So when file sizes do not come out to an even multiple of the cluster size, extra space must be used to hold the file (up to the next multiple of the cluster size). On the typical partition, this means that on average (cluster size)/2 * (number of files) worth of space is lost in this way. If no cluster size is specified during format, defaults are selected based on the size of the partition.

NTFS File System Conversion
Windows supports two disk file systems: the FAT file system and the NTFS file system. This article explains how to convert a FAT partition into an NTFS partition, and the considerations to take into account. For additional informationabout the differences between the FAT and NTFS file systems, as well as the advantages and disadvantages of each, click the following article number to view the article in the Microsoft Knowledge Base: The Convert.exe utility is supplied with Windows to convert a FAT partition into an NTFS partition. Use of Convert.exe is straight forward, but there are considerations that should be taken into account before using the utility.
NTFS New Capabilities and Features
Windows 2000 contains new features that are available only with the NTFS file system. This article outlines the features and advantages of converting to the NTFS file system with Windows 2000. These features require on-disk data structures that make these volumes unavailable to Windows NT 4.0-based computers. In anticipation of dual- boot scenarios, upgrade Windows NT 4.0 to SP4 before starting the Windows 2000 installation. The version of NTFS included with Windows 2000 cannot be interpreted correctly by Windows NT 4.0. However, there is an updated Ntfs.sys driver in Windows NT 4.0 Service Pack 4 that enables Windows NT 4.0 to read from and write to NTFS volumes in Windows 2000.This article describes how to restore the default NTFS file system permissions for Microsoft Windows 2000. Windows 2000 includes Security Configuration templates that contain the default settings for NTFS permissions, for registry permissions, for default user rights, and for others. You can use the Security Configuration templates in conjunction with the Security Configuration and Analysis snap-in from Microsoft Management Console (MMC) to restore the default security settings in Windows 2000.

NTFS Evolution
Welcome to Part II of the Ars Technica NTFStock! For those who didn't see Part I , I'll fill you in on what I wrote about and you can decide if you want to go back and read it. Part I was concerned with both the origins of NTFS (from both FAT and HPFS development efforts), and the inter-workings of NTFS as it stands in Windows NT 4.0. It's worth a read , IMHO (but of course, I wrote it)!
The documentation for the NTFS file system states that NTFS supports multiple streams of data; however, the documentation does not address the syntax for the streams themselves. Alternate data streams are strictly a feature of the NTFS file system and may not be supported in future file systems. However, NTFS will be supported in future versions of Windows NT. Future file systems will support a model based on OLE 2.0 structured storage (IStream and IStorage). By using OLE 2.0, an application can support multiple streams on any file system and all supported operating systems (Windows, Macintosh, Windows NT, and Win32s), not just Windows NT.
NTFS Alternate Data Streams Usage
NTFS Reader DOS Boot Disk provides read access to NTFS drives from the MS DOS environment. It supports long filenames as well as compressed and fragmented files. NTFS Reader for DOS allows you to preview the files on NTFS and copy them from NTFS to FAT volumes or network drives. In order to use the software you need to copy the readntfs.exe file to a bootable floppy disk and boot from it. Note : You can use NTFS Reader for DOS to access NTFS drives in Windows 98 95 and 3.1. This is a DOS program, but it can be run from Windows.

NTFS Date and Time Stamps
This article describes how file and folder date and time stamps (created or modified) are displayed based on the file system that is in use (FAT or the NTFS file system), and the partition (whether the action occurred on the same partition or across partitions).NTFS Disk Space Problems
File attributes or NTFS permissions prevent files or folders from being either displayed or accessed when you use either Microsoft Windows Explorer or a Windows command prompt. Disk space can be consumed only by files and folders that include internal NTFS metafiles, for example the MFT, folder indexes, and so on. Multiples of a cluster consume all file space allocation. A cluster is a collection of contiguous sectors.Webroot Anti-Virus with Spy Sweeper 2011 This anti-virus software is a very powerful protection against viruses, rootkits, key loggers, spyware and many other online threats.

NTFS Alternate Data Streams Explained
Note Internally, NTFS treats folders as a special type of file. Therefore, the word "file" in this article indicates either a file or folder. Cause 1: The file uses an ACL
