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. [2]
The developers of NTFS-3G later formed a company, Tuxera Inc., to further develop the code. NTFS-3G is now the free "community edition", [2] while Tuxera NTFS is the proprietary version. In 2021, Linus Torvalds merged a different NTFS (experimental as of 6.0) [7] implementation called NTFS3 into the Linux kernel 5.15. [8]
The ntfs.sys released with Windows Vista made the functionality available to user mode applications by default. Since NTFS 3.1, a symbolic link can also point to a file or remote SMB network path. While NTFS junction points support only absolute paths on local drives, the NTFS symbolic links allow linking using relative paths.
The maximum NTFS volume size implemented in Windows XP Professional is 2 32 − 1 clusters, partly due to partition table limitations. For example, using 64 KB clusters, the maximum size Windows XP NTFS volume is 256 TB minus 64 KB. Using the default cluster size of 4 KB, the maximum NTFS volume size is 16 TB minus 4 KB.
The mounted volume is not limited to the NTFS filesystem but can be formatted with any file system supported by Microsoft Windows. However, though these are similar to POSIX mount points found in Unix and Unix-like systems, they only support local filesystems; on Windows Vista and later versions of Windows, NTFS symbolic links can be used to ...
While no production Unix kernel has yet adopted transactions, proof-of-concept research prototypes have been developed for Linux, including the Valor file system [12] and the TxOS kernel. [13] Microsoft Windows has added transactions to its NTFS file system, [14] but Microsoft discourages their use, and has indicated that they may be removed in ...
docs.microsoft.com /en-us /windows /win32 /ktm /kernel-transaction-manager-portal Kernel Transaction Manager ( KTM ) is a component of the Windows operating system kernel in Windows Vista and Windows Server 2008 that enables applications to use atomic transactions on resources by making them available as kernel objects.
I did not revisit this talk as the article did not differentiate NTFS 3.1 versions by LFS, except in the journaling section, yet what I was trying to infer is that if one dual-booted Windows 7 and then Windows 8 or 10 or 11 without disabling chkntfs.exe, there was a potential for a dirty bit on the Windows 7 partition, asking for recovery (that ...
