Junction Points. 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. Junction Link Magic automatically lists existing junction points, and it offers an easy interface to add, modify or remove junction points. Junction Link Magic is freeware. 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.

Junction Link Magic will list all 3 types, not only junction links.
A junction point is a technology for a folder to be grafted into another folder on the same local computer. 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.
Change in Windows XP and in Windows Server 2003 In Windows XP and in Windows Server 2003, the defrag utility defrags the MFT. 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. An MFT can be too big if a volume used to have lots of files that were deleted. NTFS uses MFT entries to define the files to which they correspond. Note The results returned by the dir command may not be current. 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.
Please keep in mind that two conditions must be met in order for this information to apply to your issue: File system must be NTFS. FAT currently does not keep a copy of the bootsector. You must be able to boot your machine to NT. NOTE: If you cannot Boot into NT or move the drive to another NT machine then follow Knowledge Base Article: ( ) : How to recover from a corrupt NTFS bootsector 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). Note: Recovering Bootsectors of Primary Partitions. NTFS Directories and Files. NTFS and FAT Default Cluster Size. All file systems that are used by Windows organize your hard disk based on cluster size (also known as allocation unit size).
Cluster size represents the smallest amount of disk space that can be used to hold a file. When file sizes do not come out to an even multiple of the cluster size, additional space must be used to hold the file (up to the next multiple of the cluster size). On the typical hard disk partition, the average amount of space that is lost in this manner can be calculated by using the equation (cluster size)/2 * (number of files). If no cluster size is specified when you format a partition, defaults are selected based on the size of the partition. These defaults are selected to reduce the space that is lost and to reduce the fragmentation that occurs on the partition.
A hard disk partition (also known as a volume) can be formatted to NTFS, FAT, or exFAT. Default cluster sizes for NTFS The following table describes the default cluster sizes for NTFS. Applies to. 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: ( ) Overview of FAT, HPFS, and NTFS file systems NOTE: Windows NT 4.0 no longer supports the HPFS file system.
The Convert.exe utility is supplied with Windows to convert a FAT partition into an NTFS partition. The following limitations should be recognized before converting a FAT partition to NTFS: The conversion is a one-way process. To convert a FAT partition to NTFS, perform the following steps. Convert cannot gain exclusive access to the [driveletter]:, so it cannot convert it now.
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. New features of the NTFS 3.0 file system include: Disk quotas. Administrators can limit the amount of disk space users can consume on a per-volume basis.

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. To do so, follow these steps: Click Start, and then click Run. For additional information about Default NTFS Permissions, click the following article numbers to view the articles in the Microsoft Knowledge Base: ( ) Default NTFS permissions in Windows 2000 ( ) Default NTFS permissions in Windows NT.
NTFS Evolution. By Matt "Panders" Anderson 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)! But, if for some reason you happen to be dead set against doing so, don't fret. Even though the upcoming discussion is, for the most part, built upon the previous article, I've tried to make it as accessible as possible apart form the Part I material. What's in Part II? Prelude to NTFS 5: the NT 4.0 SP4 NTFS.SYS driver I wanted to say a few things right here up front about this new ntfs.sys driver and what you need to be aware of before installing Windows 2000 to dual boot on your system.
New built in quotas! New? NTFS Alternate Data Streams Usage. 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. The Windows NT Resource Kit documents the stream syntax as follows: filename:stream 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.
The following sample code demonstrates NTFS streams: Sample Code The file size obtained in a directory listing is 16, because you are looking only at "testfile", and therefore type testfile produces the following: However type testfile:stream produces the following: -or- Reader for DOS. NTFS Date and Time Stamps. NTFS Disk Space Problems. The disk space allocation of an NTFS volume may be misreported for any of the following reasons: The cluster size of the NTFS volume is too large for the average-sized files that are being stored.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.The folder path exceed 255 characters.Folders or files contain invalid or reserved file names.NTFS metafiles (such as the Master File Table [MFT]) have grown and cannot be unallocated.Files or folders contain alternate data streams.NTFS corruption causes Windows to report free space as being in use.Other NTFS features cause file-allocation confusion.
The Cluster Size Is Too Large 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. NTFS Alternate Data Streams Explained. NTFS. NTFS File Or Folder Deletion Problems. 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 You may not be able to delete a file if the file uses an Access Control List (ACL). To resolve this issue, change the permissions on the file. Administrators have the implicit ability to take ownership of any file even if they have not been explicitly granted any permission to the file. You cannot use certain security tools to display or to modify permissions because the file has a non-canonical ACL To work around this issue, use another tool (for example, a later build of Cacls.exe). The Access Control Entries (ACEs) in an ACL have a certain preferred sequence depending on their type. Cause 2: The file is being used You may not be able to delete a file if the file is being used. . ( ) How to display a list of processes that have files open ( ) NTFS Permissions Inheritance. This step-by-step article describes how to control NTFS permissions inheritance. The following operating systems support the Windows NT File System (NTFS): Microsoft Windows XPMicrosoft Windows 2000Microsoft Windows NT Drives and volumes that are formatted with the NTFS file system can use NTFS file-system permissions.
NTFS file-system permissions provide the administrator with the highest level of access control that is available on Windows operating systems. When you create a folder on an NTFS partition or volume, Full Control/Everyone are the default NTFS permissions on the folder and all objects that are created in the folder. All subfolders of the parent folder have the same permissions. You can configure the default permissions inheritance behavior to allow customized permissions for subfolders and files.
