For each file (or directory) described in the MFT record, there is a linear repository of stream descriptors (also named attributes), packed together in one or more MFT records (containing the so-called attributes list), with extra padding to fill the fixed 1 KB size of every MFT record, and that fully describes the effective streams associated ...
Typical file attributes may, for example, indicate or specify whether a file is visible, modifiable, compressed, or encrypted. The availability of most file attributes depends on support by the underlying filesystem (such as FAT, NTFS, ext4) where attribute data must be stored along with other control structures. Each attribute can have one of ...
An NTFS reparse point is a type of NTFS file system object. It is available with the NTFS v3.0 found in Windows 2000 or later versions. Reparse points provide a way to extend the NTFS filesystem. A reparse point contains a reparse tag and data that are interpreted by a filesystem filter driver identified by the tag.
In NTFS, an entity in the filesystem fundamentally exists as: a record stored in the MFT of an NTFS volume, the MFT being the core database of the NTFS filesystem; and, any attributes and NTFS streams associated with said record. A link in NTFS is itself a record, stored in the MFT, which "points" to another MFT record: the target of the link
Determines if the file systems supports multiple data streams. NTFS refers to these as alternate data streams, HPFS as extended attributes and HFS calls them forks. Namespace Lists the characters that are legal within file and directory names. Native operating system The name of the operating system in which this file system debuted. Partition ...
NTFS has a master file table (MFT) storing files in a B-tree. Each entry has a "fileID", analogous to the inode number, that uniquely refers to this entry. [25] The three timestamps, a device ID, attributes, reference count, and file sizes are found in the entry, but unlike in POSIX the permissions are expressed through a different API. [26]
The original File Allocation Table file system has a per-file all-user read-only attribute. NTFS implemented in Microsoft Windows NT and its derivatives, use ACLs [1] to provide a complex set of permissions. OpenVMS uses a permission scheme similar to that of Unix. There are four categories (system, owner, group, and world) and four types of ...
Additional attributes can be associated on file systems, such as NTFS, XFS, ext2, ext3, some versions of UFS, and HFS+, using extended file attributes. Some file systems provide for user defined attributes such as the author of the document, the character encoding of a document or the size of an image.
