1. Open Google Colab and click “New notebook”.
2. Open the files tab in the sidebar and mount google drive.
3. Paste the following code into a cell and run it (Ctrl+Enter).
!wget -P /content/drive/My\ Drive/upload_folder http://www.url.to/your/file.txt
upload_folder with an existing directory on your google drive (into which the file will be uploaded) and
http://www.url.to/your/file.txt with your files’s url.
I’ve found this method to be much faster than downloading the file onto my machine and then uploading it to google drive.
