Good afternoon! For your consideration - we need feedback, please!
New is: - 2nd spring release - Support for Win32 named streams/Alternate Data Streams (ADS), if the NFSv4.x server supports NFS named attributes (e.g. Solaris >= 11.4, Illumos, FreeBSD >= 15.0, ...), incl. stream renaming - Windows Server 2025 is now supported (NFS client, and using WS2025 as NFSv4.1 server) - Windows ARM64/aarch64 support added - Windows FCB collapsing is now supported, multiple Windows file handles can share a single NFS file handle, if access attributes match - Now supports case-insensitive NFS filesystems - Copy acceleration (Win32 read/write offload) via server-side NFSv4.2 COPY for copy, xcopy, Windows Explorer, ..., works even if the exported filesystem does not support block cloning - New tool to manage machine-wide mounts for all logons/services: /sbin/nfs_globalmount.exe - Better FreeBSD NFS server compatibility - Volume label is now an URL to the NFS server, e.g. nfs://hostname/ - winsg.exe now supports PowerShell directly- The NFS driver and wings.exe now support non-ASCII characters (e.g french circumflex) - Sparse file support (https://en.wikipedia.org/wiki/Sparse_file) for HPC environments - Symlink conversion, to make Windows symlinks exchangeable with other NFS clients on other platforms - Windows Server 2019 NFSv4.1 nfsd, Windows Server 2022 NFSv4.1 nfsd, Solaris 11.4 NFSv4.1 nfsd, Illumos NFSv4.2 nfsd and FreeBSD >= 14 nfsd support - MSYS2 support Ced ---------- Forwarded message --------- From: Roland Mainz <[email protected]> Date: Mon, 19 Jan 2026 at 11:16 Subject: [Ms-nfs41-client-devel] [Announcement] NFSv4.2/NFSv4.1 filesystem client Windows driver binaries for Windows 10/11+WindowsServer 2019/2022/2025 for testing, 2026-01-19 ...

A *.cer certificate file is supplied which can be imported into the Windows Defender to whitelist the binaries if this happens. - Support for |FSCTL_DUPLICATE_EXTENTS_TO_FILE|, which allows Windows 11 applications which use |CopyFile2()| (like cmd.exe copy, xcopy.exe etc) to copy files via block cloning. Requires NFSv4.2 NFS server with { CLONE, SEEK, DEALLOCATE } support, exporting a filesystem which supports block cloning (e.g. btrfs, xfs). This includes correct cloning of sparse files. - Sparse file support (requires NFSv4.2 server { SEEK, ALLOCATE, DEALLOCATE } and the |FATTR4_WORD1_SPACE_USED| attr), including hole/data range enumeration, punching holes etc., e.g. $ fsutil sparse queryrange mysparsefile # and Win32 named stream support - Improved Windows Extended Attribute (EA) support (requires NFS >= v4.1 server with "Named Attribute" support ("OPENATTR")), including create/read/write/delete - Improved WSL support - Support for Storage32-API (e.g. enables use of *.msi installer files on NFS filesystems) - Cygwin /usr/bin/svn and Windows '/cygdrive/c/Program Files/Git/cmd/git' now work - Illumos NFSv4.2 server is now supported - Solaris 11.4 NFSv4.1 server is now supported - Windows Server 2022 NFSv4.1 server is now supported (compared to WS2019 this NFS server version has ACL support) ** Please send comments, bugs, test reports, complaints etc. to the MailMan mailing list at https://sourceforge.net/projects/ms-nfs41-client/lists/ms-nfs41-client-devel ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) [email protected] \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 3992797 (;O/ \/ \O;) _______________________________________________ Ms-nfs41-client-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/ms-nfs41-client-devel -- Cedric Blancher <[email protected]> [https://plus.google.com/u/0/+CedricBlancher/] Institute Pasteur -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
