Using Python (`boxsdk`, `requests`, and `tqdm` modules), all files from a Box folder -- specified by ID -- are downloaded via URL. Yes the binary can simply be downloaded with the Box SDK methods.

DownloadBoxFilesPython.py

from boxsdk import DevelopmentClient
import requests
from tqdm.auto import trange

client = DevelopmentClient()
user = client.user().get()

folder = client.folder(folder_id='XXXXXXXXXXXX')
files = [item for item in folder.get_items()]

print('Beginning file download with requests...')

for i in trange(len(files)):
    url = files[i].get_download_url()
    r = requests.get(url)
    
    with open('../../Folder/'+item.name, 'wb') as f:
        f.write(r.content)
