Google Drive apparently went down for a couple of hours this morning. (I missed it. I was in a meeting.) This is a good reminder that you need to maintain the ability to work with your documents when the Internet or the cloud service itself is unavailable. Google has a page about setting up offline access for Google Drive documents. Do it now while you’re thinking about it.
On the Mac, the Google Drive app created a folder in my home folder containing all of my Drive files with extenions like “.gdoc”, “.gslides” and “.gsheet”. I presume that offline Google Drive works the same way on Windows. On Linux, I enabled offline access from the web, then installed a Chrome app.
