python - Extracting large files with zipfile -


i'm trying extract zip file of 1.23 gb zipfile library. gives following error:

 compression type 9 (deflate64)

here's code:

zip_ref = zipfile.zipfile(filepath, 'r') zip_ref.extractall(newpath)

it gives error while trying extract contents.

is there way unzip large zip files python?

this happens because compression method not implemented in zipfile module.

some discussion issue here: https://bugs.python.org/issue14313

the fix raise notimplementederror instead of adding support compression method.

suggested solutions:

  • if possible, recompress file using standard deflate method.
  • use subprocess module invoke system unzip command, asssuming installed on os (if supports compression method, i'm not sure. know 7-zip supports method.).
