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.
Junction points are NTFS reparse points and operate similarly to symbolic links in Unix or Linux, but are only defined for directories, and may only be absolute paths on local filesystems (as opposed to remote filesystems being accessed). They are created and behave in a similar way to hard links, except that if the target directory is renamed ...
Reparse Point (L): The file or directory has an associated re-parse point, or is a symbolic link. Offline (O): The file data is physically moved to offline storage (Remote Storage). Sparse (P): The file is a sparse file, i.e., its contents are partially empty and non-contiguous. Temporary (T): The file is used for temporary storage.
Microsoft includes several default tags including symbolic links, directory junction points and volume mount points. When the Object Manager parses a file system name lookup and encounters a reparse attribute, it will reparse the name lookup, passing the user controlled reparse data to every file system filter driver that is loaded into Windows ...
Mount points can be created in a directory on an NTFS file system, which gives a reference to the root directory of the mounted volume. Any empty directory can be converted to a mount point. The mounted volume is not limited to the NTFS filesystem but can be formatted with any file system supported by Microsoft Windows.
Transactional NTFS (abbreviated TxF [1]) is a component introduced in Windows Vista and present in later versions of the Microsoft Windows operating system that brings the concept of atomic transactions to the NTFS file system, allowing Windows application developers to write file-output routines that are guaranteed to either succeed completely or to fail completely.

If a symbolic link is deleted, its target remains unaffected. If a symbolic link points to a target, and sometime later that target is moved, renamed or deleted, the symbolic link is not automatically updated or deleted, but continues to exist and still points to the old target, now a non-existing location or file.
A snapshot is a read-only point-in-time copy of the volume. Snapshots allow the creation of consistent backups of a volume, ensuring that the contents do not change and are not locked while the backup is being made. The core component of shadow copy is the Volume Shadow Copy service, which initiates and oversees the snapshot creation process.
