Course Sharing Network Browser (CSN Browser) is built base on the Chromium browser which will help to protect the shared link but allow to download the files directly from the Cloud server so it should be much quicker especially for the large packages.
You can download every single file, a folder as ZIP, the whole package as ZIP or you can save the files to your pCloud account.
For packages more than 1GB we would suggest using CSN Browser to download if download via our server proxy, the large packages may get corrupted.
Note: you may get the "Windows protected your PC" warning. This happens because CSN-Browser is not a signed app. You can ignore it and hit run anyway to install the browser.
