  • This pre-release contains FUSE 3.2 support. If you have a FUSE 3.2 file system I would love to hear your feedback.
  • This pre-release includes signed drivers for Windows 7, 8, 10, but not Server 2016.


  • FUSE3 API (version 3.2) is now available. The FUSE2 API (version 2.8) also remains supported.
  • New Control file system operation allows sending custom control codes to the file system using the Windows DeviceIoControl API. FUSE ioctl is also supported.
  • New SetDelete file system operation can optionally be used instead of CanDelete. SetDelete or CanDelete are used to handle the file "disposition" flag, which determines if a file is marked for deletion. See the relevant documentation for more details.
  • FlushAndPurgeOnCleanup has now been added to the .NET API. (GitHub PR #176; thanks @FrKaram.)
  • New sample file system "airfs" contributed by @JohnOberschelp. Airfs is an in-memory file system like Memfs on which it is based on; it has received substantial improvements in how the file name space is maintained and has been modified to use modern C++ techniques by John.
  • New sample file system "passthrough-fuse3" passes all operations to an underlying file system. This file system is built using the FUSE3 API. It builds and runs on both Windows and Cygwin.
  • The FUSE layer now supports multiple file systems within a single process. This is a long standing problem that has been fixed. (GitHub issue #135.)
  • The FSD includes an experimental fix for a Windows problem: that case-sensitive file systems do not work properly when mounted as directories. See the relevant FAQ entry.
  • The FSD includes a fix for an incompatibility with DrWeb Antivirus. (GitHub issue #192.)
