Google Drive always allows you to upload files, images, and folders through their web portal so you can work on the uploaded files anywhere and anytime. But the way it allows you to upload is so out-dated that it definitely needs a re-makeup.
Not anymore, with a new update released on Nov. 20, 2015, you can now simply drag a file, a bunch of files, or even an entire folder from your local computer directly into any Google Drive’s folders or subfolders. Files or folders will get uploaded to the Drive immediately.
Note that in order to get this cool new feature to work, you will need the latest versions of Chrome or Firefox. Unfortunately, it doesn’t work on Microsoft Edge at the moment.
