Downloading large amount of data from a secure link

Question

I've received a secure link to a directory on a client's SharePoint for the purpose of sharing a non-trivial amount of data, probably about 30GB. I can download single directories and it works, but it's a chore having to click everything and I will need to do that often. I tried downloading it all by selecting every top-level directory and clicking "Download", but the file that gets downloaded is corrupted — ZIP reports missing central directory, so I assume it's truncated during download. The "Open in File Explorer" link returns Access Denied. Are there any other options for automating download of this directory?

Depending on the version of SharePoint you have you can try to sync the library using OneDrive. If it is a option you should see a "Sync" button in the library.
