Windows fuse support

[Anachron]

I've heard about Winfsp landing 1.0 which gives Windows the ability to use a fuse-like fs.

I hope someone can make borg mounts work on Windows!

I did not test with cygwin, latest windows branch errors on python side: ImportError: No module named 'llfuse'
I'll check if llfuse can use winfsp or if winfsp native api is any good.
Not going to port llfuse, winfsp looks good.

Hello, I am the author of WinFsp and I am happy to help.

WinFsp has a native API, but it also has a high-level FUSE API. It does not have a low-level FUSE API, because the low-level FUSE API is very "VFS" specific and not a good fit for Windows. [I would however consider adding a low-level FUSE API if enough people asked for it.]

I have also ported fusepy to Windows: port. I understand that this project uses llfuse, so this may not be of much use to you.

Just asked Junie AI for something like FUSE on windows:

FUSE Alternatives for Windows

Yes, there are several alternatives to FUSE (Filesystem in Userspace) for Windows:

1. WinFsp (Windows File System Proxy) - The most popular and mature option, providing FUSE-like functionality for Windows. It allows developers to create user-mode file systems on Windows.

   • Website: https://github.com/winfsp/winfsp
   • It's actively maintained and used by many projects

2. Dokany (formerly DokanY) - Another popular userspace file system library for Windows.

   • Website: https://github.com/dokan-dev/dokany
   • Used by several projects including SSHFS-Win

3. CBFS (Callback File System) - A commercial solution from Callback Technologies.

   • Provides a framework for creating virtual file systems

4. Windows Projected File System (ProjFS) - Microsoft's own API for creating virtualized file systems, introduced in Windows 10.

   • Used by Microsoft's own Git Virtual File System (GVFS)

5. FUSE for Windows - There are also projects that port FUSE directly to Windows, such as:

   • Cygwin FUSE
   • WSL (Windows Subsystem for Linux) which can run Linux FUSE implementations

WinFsp is generally considered the closest equivalent to Linux's FUSE in terms of functionality and developer experience on Windows.

#9213 was just merged into master branch and will be in 2.0.0b20.

I have seen some windows support code in mfusepy code, but did not test it.

If anybody is interested in working on that:

Guess the first step would be to extend CI testing at mfusepy project to include Windows.
