    Windows 10 & 11 Hard Links Guide: Create NTFS File Links With mklink and PowerShell

    Hard links are one of the oldest tricks in NTFS, and one of the least used. They let one file appear in several folders without a second copy of its data. Here is how they work, how to create them, and where they go wrong. What a hard link actually is Microsoft's fsutil documentation describes a...

    ReactOS Can Now Install on NTFS Partitions, but Driver Limits Remain

    ReactOS can now be installed on an NTFS partition and run from it. The project has been working toward this for nearly a decade, and it is a real milestone. It is also a long way from a finished filesystem. What actually changed ReactOS said on X that, after nearly a decade, its NTFS driver got...

    Why Windows 11 Still Uses kernel32.dll and Other 8.3 System Filenames

    Pop open the C:\Windows\System32 folder on a modern Windows 11 PC, and the illusion of a sleek, contemporary operating system evaporates in a hurry. Beneath the rounded corners, translucent Mica surfaces, and WinUI 3 dialogs sits a digital museum of file names that look as though they were...

    Linux 7.3: Threadripper Storage Gains, Windows NTFS Compression Support and Valve Gaming Updates

    There is an old rule in enterprise IT and workstation engineering: you can buy the most expensive silicon on the planet, but if the operating system kernel is dragging its feet on thread scheduling or storage I/O, you are essentially driving a Formula 1 car through a school zone. Every few...

    Windows 11 4TB SSD Setup: Should You Use 64KB NTFS Clusters or Partition Your Drive?

    When you drop a fast, high-capacity 4TB NVMe SSD into a modern Windows 11 rig, the path of least resistance is to initialize the drive, accept the default formatting prompts, and enjoy your vast new digital real estate.

    Windows 10 & 11 Hard Links: Create Files with mklink /H, Verify and Avoid Common Pitfalls

    Ask a Windows user where a file lives and they'll name a folder. In fact, an NTFS file can have several names in several folders at once, with only one copy of its data on disk. MakeUseOf's Afam Onyimadu tested this with a hard link. This is a built-in feature, and one command creates it. The...

    Fix Common Windows File Errors: Blocked Downloads, Long Paths, Access Denied and Locked Files

    Windows file errors often look random. An installer refuses to run, a copy stops halfway, or a folder in your own profile answers "Access is denied." TweakTown's new guide argues that most of these failures come from a few long-standing file-system rules. After checking it against Microsoft's...

    WizTree Fast NTFS MFT Scans Explained: Admin Setup, Folder Modes and WinDirStat

    WizTree reportedly mapped a relatively empty 1TB SSD in just 0.9 seconds in XDA writer Tanveer Singh’s testing. The explanation is less magic trick than clever bookkeeping: on an NTFS volume, WizTree can read the Master File Table directly instead of walking through the drive’s directory...

    Windows 11 8.3 Names: Disable Creation, Strip Aliases Carefully

    Windows 10 and Windows 11 can still create 8.3 short filenames, the legacy MS-DOS aliases stored next to long filenames on NTFS. A Reddit user reported this month that turning off that behavior and removing existing aliases made File Explorer and file transfers much faster. Microsoft's...

    Windows File Tunneling Can Preserve Deleted File Timestamps

    Windows can give a newly created file the creation timestamp of a file you just deleted when you reuse its name in the same folder. The behavior, called file system tunneling, is a documented compatibility feature of filesystems including NTFS and FAT—not a new Windows update or, by itself...

    Windows FILETIME: Why 1601 Timestamps Can Mislead

    MakeUseOf is right about the oddity at the center of Windows file timestamps: the Win32 FILETIME format counts 100-nanosecond intervals from January 1, 1601, at 00:00:00 UTC. But its headline overstates the case. Windows does not mean that every file physically stores its timestamps as one...

    A downloaded file in Windows can carry provenance information that never appears in its filename, size, or ordinary File Explorer view.

    Why Documents and Settings Still Appears on Windows 11

    A root-level C:\Documents and Settings entry can look like a leftover from a much older PC: it may appear in a broad directory listing, yet opening it in File Explorer or asking a backup tool to enumerate it can result in Access is denied. On a typical modern Windows installation, that does not...

    Work Folders: Which Windows Folders Are Blocked and How to Fix It

    Microsoft’s Work Folders documentation makes a short but important point that trips up administrators and power users alike: some folders on a Windows PC simply cannot host Work Folders because they are reserved by the operating system or are already protected by file encryption. The official...
