4 Dropbox
You’ve probably heard of Dropbox. Chances are, you use Dropbox. But it’s such a no-brainer of an application that it warrants mentioning here (especially for all of the Mac users who haven’t heard of or don’t use it).
Dropbox is a cloud storage solution, and a powerful one at that. But it also integrates extremely well with macOS. When you download and sin tall Dropbox, it’ll place a folder into Files, so you can easily add to and access your cloud-based data. With an iOS app and a browser-based platform, you’ll be able to view your files basically anywhere that you have the internet.
