File transfer API

Hi,

I started to become familiar with the Dropbox API (Python). I am looking for the API that will transfer a file from my Windows 10 machine to my Dropbox account. Looking at this sample code on the Dropbox website to backup a file:

with open(LOCALFILE, 'rb') as f:
    # We use WriteMode=overwrite to make sure that the settings in the file
    # are changed on upload
    print("Uploading " + LOCALFILE + " to Dropbox as " + BACKUPPATH + "...")
    try:
        dbx.files_upload(f.read(), BACKUPPATH, mode=WriteMode('overwrite'))
    except ApiError as err:
        ...........

Is there another API that does file transfer, or this is how the file transfer is carried out by reading bytes from the source and writing to the destination (Just want to make sure I am not missing something)?

 

Thanks in advance
