!pip install pyunpack
!pip install patool
from pyunpack import Archive
Archive('Location of the rar file').extractall('Location where you want to have the folder')

Check out this code snippet

Really simple and super fast

You can write a simple python code to extract the zip-file directly in your google drive from google colab.

Note: For this code to work, you'll need to install a module named rarfile in colab. You can do so by the following code snippet:

pip install rarfile

Without getting into the details of how it works, go ahead and copy the code snippet below into google colab and run the cell.

def unrar(dpath,xpath):
  for rar in os.listdir(dpath):
    filepath = os.path.join(dpath, rar)
    with rarfile.RarFile(filepath) as opened_rar:
      for f in opened_rar.infolist():
        print (f.filename, f.file_size)
        opened_rar.extractall(xpath)

unrar(dpath,xpath)

Here, dpath is the path directory where your .rar file is located. xpath is where you want to extract it.

Try this:

pip install patool
import patoolib
patoolib.extract_archive("foo_bar.rar", outdir="path here")

I think no need to give the path inside double quotes. – Kirushikesh Nov 02 '21 at 06:07

I have tried lots of solutions since then, but the best one has been to get the file from drive to collab's storage using "rsync" Linux command (install rsync using "!apt install rsync") and then "unzip" command. It is lightning fast after that (71.32MB/s).
