Introduction

If you use Linux and occasionally run Windows applications, whether via native Wine or through gaming layers like Proton, you’ll appreciate what just dropped in Wine 10.19. Released November 14 2025, this version brings a major enhancement: official support for Windows reparse points, a filesystem feature many Windows apps rely on, and a host of other compatibility upgrades.

In simpler terms: Wine now understands more of the Windows filesystem semantics, which means fewer workarounds, better application compatibility, and smoother experiences for many games and tools previously finicky under Linux.

What Are Reparse Points & Why They Matter

On Windows, a reparse point is a filesystem object (file or directory) that carries additional data, often used for symbolic links, junctions, mount points, or other redirection features. When an application opens or queries a file, the OS may check the reparse tag to determine special behavior (for example “redirect this file open to this other path”).

Because many Windows apps, installers, games, DRM systems, file-managers, use reparse points for features like directory redirection, path abstractions, or filesystem overlays, lacking full support for them in Wine means those apps often misbehave.

With Wine 10.19, support for these reparse point mechanisms has been implemented in key filesystem APIs: for example NtQueryDirectoryFile, GetFileInfo, file attribute tags, and DeleteFile/RemoveDirectory for reparse objects.

This means that in Wine 10.19:

• Windows apps that create or manage symbolic links, directory junctions or mount-point style re-parsing will now function correctly in many more cases.

• Installers or frameworks that rely on “when opening path X, redirect to path Y” will work with less tinkering.

• Games or utilities that check for reparse tags or use directory redirections will have fewer “stuck” behaviors or missing files.

In effect, this is a step toward closer to native behavior for Windows file-system semantics under Linux.

Other Key Highlights in Wine 10.19

Beyond reparse points, the release brings several notable improvements:

• Expanded support for WinRT exceptions (Windows Runtime error handling) meaning better compatibility for Universal Windows Platform (UWP) apps and newer Windows-based frameworks.

• Refactoring of “Common Controls” (COMCTL32) following the version 5 vs version 6 split, which helps GUI applications that rely on older controls or expect mixed versions.
