Google completely revamped the desktop Google Drive client this year with the move to Backup & Sync. The initial rollout was a bit of a mess with Google essentially breaking Drive for some people. It eventually worked all that out, and Backup & Sync has been running smoothly since then. There haven't been many feature additions, but there's a big one rolling out now. In the latest version, you have more control over which files are synced, and it's easier to add new folders to Drive.
The latest version of the Backup & Sync client has build number 3.38.7642.3857. Here's what you can expect to see when you update.
The toggle for photos and videos will be handy if you use Drive mainly for camera backup. You don't need a handful of documents and folders in the way of your pics, right? On the flip side, you can specifically exclude files types from Backup & Sync in the new update. In the advanced settings, you can add file extensions for the app to ignore. You can add new items to Drive much more easily, too. Just right-click on a folder and select "Sync this folder" to get it in Google Drive.
