复制文件时发生错误 shutil.copy() PYTHON

Question

我正在尝试将 tif 文件从包含硬盘驱动器上各种文件夹的各种文件夹复制到新位置，但出现错误 到目前为止我的代码是

location = (r'D\Folder\subfolder\[1] subsubfolder\photos\Montage')
dest = (r'D\Folder\subfolder\[1] subsubfolder\')

keyword = 'Red_'


for subdir, dirs, files in os.walk(source):
    for file in files: 
        if keyword in file and file.endswith(".tif"):
                    
            try: 
                shutil.copytree(os.path.join(location, file), os.path.join(dest, file))
                print("File copied Succesfully")
            
            except shutil.SameFileError:
                print("Source and destination respresents the same file.")
                
            except PermissionError:
                print("Permission denied.")
                
            except:
                print("Error occured while copying files.")
            

复制所有文件时出现错误。

为什么我会收到这个错误：
