예외

Microsoft Windows NT를 실행하는 컴퓨터에 대상 파일이 열려 있거나 메모리 매핑된 경우The target file is open or memory-mapped on a computer running Microsoft Windows NT.

또는-or- 파일에 대해 열린 핸들이 있고 운영 체제가 Windows XP 또는 이전 버전입니다.There is an open handle on the file, and the operating system is Windows XP or earlier. 이 열린 핸들은 디렉터리 및 파일을 열거하면 발생할 수 있습니다.This open handle can result from enumerating directories and files. 자세한 내용은 방법: 디렉터리 및 파일 열거를 참조하세요.For more information, see How to: Enumerate Directories and Files.

호출자에게 필요한 권한이 없는 경우The caller does not have the required permission.

경로가 디렉터리인 경우The path is a directory.
