Apparently you can save it to Google drive then download the Google drive program and make that folder available offline so it downloads it to the computer.
When you setup the Google Takeout export choose Save in a Google Drive folder
Install the Google Drive PC client (Drive for desktop)
It will create a new drive (i.e. G:) in your explorer. Right click on the takeout folder and select “Make available offline”. All files in that folder will be downloaded by the Google Drive Desktop in the background, and you will be able to copy to another location, as they will be local files.
