Do you mean `PHP_OS`? It could be a solution ```php if (PHP_OS === 'WINNT') { return $this->packagesPath() . '\\' . $this->vendor(); } return $this->packagesPath() . '/' . $this->vendor(); ```

I think this is the solution we are looking for. ```php public function vendorPath() { return $this->packagesPath().DIRECTORY_SEPARATOR.$this->vendor(); } public function packagePath() { return $this->vendorPath().DIRECTORY_SEPARATOR.$this->package(); } ```

bump.
