We're trying to find a forum-wide solution for broken Box links here but until then, Sunni at Plumb Bob Keep has figured out
a fix for links that won't download anymore:
It's been discovered that dead/inactive box links can be downloaded on mobile android devices like tablets or phones. For whatever reason the "mobile" version isn't blocking the downloads. However, this isn't exactly convenient if you don't have a mobile device or a lot of available storage on your device (plus having to transfer files, etc.) So, I studied the difference between the desktop box link and the mobile version. It looks like this:
Desktop -

https://m.box.com/shared_item/https%3A%2F%2Fwww.box.com%2Fs%2F812b31c6a4a50760dc74So, it seems if you can copy the group of numbers in bold in the desktop version and insert it into the base mobile link, it will take you to the mobile version of the website on your desktop browser, where you will be able to successfully download the file. Therefore, copy the group of numbers from the desktop link and paste at the end of the following of the mobile link:
