使用 GetAttr 函数来得知文件及目录或文件夹的属性。 'Dim MyAttr
' 假设 TESTFILE 具有隐含属性。
MyAttr = GetAttr("TESTFILE")   ' 返回 2。' 如果 TESTFILE 有隐含属性，则返回非零值。
Debug.Print MyAttr And vbHidden   ' 假设 TESTFILE 具有隐含的只读属性。
MyAttr = GetAttr("TESTFILE")   ' 返回 3 。' 如果 TESTFILE 含有隐含属性，则返回非零值。
Debug.Print MyAttr And (vbHidden + vbReadOnly)   ' 假设 MYDIR 代表一目录或文件夹。
MyAttr = GetAttr("MYDIR")   ' 返回 16。
