Salesforce is an amazing platform. You can run your entire operations and automate most of your processes. The challenge is what do you need to do when it comes to sharing a particular file or document with someone out of Salesforce. How can you share digital assets, product brochures or any document publicly? There was no solution to this until 2.2 release.
Now, you can share files and even folders with your non-salesforce users and be able to run your business efficiently.
