SHCreateDirectoryEx Function

---

Creates a new file system folder.

Syntax

int SHCreateDirectoryEx(      
    HWND hwnd,
    LPCTSTR pszPath,
    SECURITY_ATTRIBUTES *psa
);

Parameters

hwnd

[in] Handle to a parent window. This parameter can be set to NULL if no user interface will be displayed.

pszPath

[in] Pointer to a null-terminated string specifiying the fully qualified path of the directory. This string is of maximum length of 248 characters, including the null terminator.

psa

[in] Pointer to a SECURITY_ATTRIBUTES structure with the directory's security attribute. Set this parameter to NULL if no security attributes need to be set.

Return Value

Returns ERROR_SUCCESS if successful. If the operation fails, other error codes can be returned, including those listed here. For values not specifically listed, see System Error Codes .

ERROR_BAD_PATHNAME	The pszPath parameter was set to a relative path.
ERROR_FILENAME_EXCED_RANGE	The path pointed to by pszPath is too long.
ERROR_PATH_NOT_FOUND	The system cannot find the path pointed to by pszPath. The path may contain an invalid entry.
ERROR_FILE_EXISTS	The directory exists.
ERROR_ALREADY_EXISTS	The directory exists.
ERROR_CANCELLED	The user canceled the operation.

Remarks

This function creates a file system folder whose fully qualified path is given by pszPath. If one or more of the intermediate folders do not exist, they will be created as well. SHCreateDirectoryEx also verifies that the files will be visible. If not:

• If hwnd is set to a valid window handle, a message box is displayed warning the user that he or she might not be able to access the files. If the user chooses not to proceed, the function returns ERROR_CANCELLED.
• If hwnd is set to NULL, no user interface is displayed and the function returns ERROR_CANCELLED.
