How to use SharePoint Team Site files on a day-to-day-basis

I haven't set up NGSC for SharePoint, so my advice might be outdated. However, I agree that having that much content on every machine doesn't make a ton of sense unless you have heavy travelers.

I always suggest navigating to the site to work on documents. It keeps things pretty straight forward. Few caveats.

Once on the site using the menu command Open > (appliction) to edit the document. I seen users struggle with the browser editor and am always trying to streamline the experience.

If the document is one they've been working on then using the applications "Open" menu is a great option for true Office documents.

I really try to keep to the basics, letting the right tool do the heavy lifting.

I have created "My Recently Modified Document" views and the like to help find what they are working on.

Delve is a great tool for going back to what you're working on. I am really enjoying the Win 10 app and includsion of alerts in my Win 10 Action Center.
