WinFspDokan

WinFspDokan is a compatibility layer that bridges the Dokan user-space file system API with the WinFsp file system framework on Windows. It is designed to let file systems or applications that are written to the Dokan API run using the WinFsp stack, rather than requiring the Dokan kernel driver. By providing translation between the Dokan calls and WinFsp’s API, WinFspDokan aims to simplify porting Dokan-based projects to the WinFsp environment.

The core idea of WinFspDokan is to implement the Dokan interface on top of WinFsp. This means that a file system developer can implement the Dokan hooks and logic, while WinFspDokan handles mounting, I/O dispatch, and interaction with the kernel-mode components of WinFsp. The result is a Dokan-compatible file system that benefits from WinFsp’s driver model and user-space framework.

Usage typically involves having WinFsp installed, along with the WinFspDokan components, and then building or deploying a Dokan-based file system against this layer. It is commonly used by developers who want to port existing Dokan-based code to WinFsp with minimal changes, or who seek to test Dokan-compatible implementations within the WinFsp ecosystem. Some Dokan features or edge cases may vary in support depending on versions and the specific file system being implemented.

Licensing and availability are governed by the licenses of the underlying components (WinFsp and Dokan) and the WinFspDokan project itself. Prospective users should consult the project repository and documentation for current status, compatibility notes, and installation instructions.
