Hi @ifrh ,

I changed the link to point directly to the dokan version 1.0.1 https://github.com/dokan-dev/dokan-sshfs/commit/b4d90abe18815a58efac4a58d5d04e8f0838840a

Windows version supported is the version supported by the dependency explained here https://github.com/dokan-dev/dokan-sshfs#environment
