Thanks for your participation in the community and let us know how else we can help!

Warm regards, 

Frances' answer does not address Keith's question. He is asking about a Chromebook, not a PC.  I am having the same problem. Are Box and Google not getting along and therefore you can't integrate Box.com into a Chromebook?

On my Chromebooks I can download the DropBox and pCloud Android apps from the Play Store and once I have signed in to these the relevant drives become available in the Chromebook Files app. This means that I can stream files to and from my Chromebook as if it were a local drive. Here's what it looks like for me

Box could possibly add this feature to their Android app and make their product a whole lot more useful to CrOS users.

Hello. I would like an answer to this also. Can you integrate your Box account with a Chromebook (not a PC) so you can download or upload files directly from Chromebook to Box account or vis versa? This is something sorely needed.
