WinFsp, Windows File System Proxy, is a set of software components for Windows computers that allows the creation of user mode file systems. In this sense it is similar to FUSE (Filesystem in Userspace), which provides the same functionality on UNIX-like computers.
Features : As a user, installing the macFUSE software package will let you use any third-party FUSE file system. Legacy MacFUSE file systems are supported through the optional MacFUSE compatibility layer.
When you want to create a new file system on Windows, for example to improve FAT or NTFS, you need to develop a file system driver. Developing a device driver that works in kernel mode on windows is extremely difficult.
