file download link to non box user, how to

Hi Susan, 

Welcome to the Box Community and thanks for your question!

You can create a "Shared Link" and set the access link to "People with the link", then enable "Allow download" option in the shared link settings to allow non-Box users to download a content you own.

To learn more about creating Shared link, set proper Shared link access permission, Share link settings, please check out the following articles:
