I want to download the folder created in colab

According to this article, there is no approval, but it seems that you can download it as a .zip or .tar file.
Original article How do I download multiple files or an entire folder from Google Colab?/Translation How do I download multiple files or entire folders from Python 3.x-Google Colab? Is this a concise answer?

I have created a zip file:

!zip-r/content/file.zip/content/Folder_To_Zip

Than I have downloaded that zip file:

 from google.colab import files
files.download("/content/file.zip")

If you don't need a subfolder, you can do it in this for loop.
Download files in folders in bulk
