using Python to copy .npz files from a folder and its subfolders, all to some other single folder

The following code copies all .npz files in folder C:/Users/toTEST into folder C:/Users/archive

import glob
import shutil
dest_dir = "C:/Users/archive"
for file in glob.glob(r'C:/Users/toTEST/*.npz'):
    print(file)
    shutil.copy(file, dest_dir)

But the toTEST folder has several subfolders, and I would also like to move their .npz files into the archive folder as well. How can this be efficiently achieved?

Solution

  • This seems to do the trick:

    import shutil
import glob

path = 'C:/Users/toTEST/**/'
dest = 'C:/Users/archive/'
pattern = '*.npz'

selectfiles = glob.glob(path + pattern, recursive=True)

for file in selectfiles:
    shutil.copy2(file, dest)
