Downloading folders from Google Cloud Storage Bucket

You can find docs on the gsutil tool here and for your question more specifically here.

The command you want to use is:

gsutil cp -r gs://bucket/folder .

This is how you can download a folder from Google Cloud Storage Bucket

Run the following commands to download it from the bucket storage to your Google Cloud Console local path

gsutil -m cp -r gs://{bucketname}/{folderPath} {localpath}

once you run that command, confirm that your folder is on the localpath by running ls command to list files and directories on the localpath

Now zip your folder by running the command below

zip -r foldername.zp yourfolder/*

Once the zip process is done, click on the more dropdown menu at the right side of the Google Cloud Console,

then select "Download file" Option. You will be prompted to enter the name of the file that you want to download, enter the name of the zip file - "foldername.zp"
