Google updated their Google Drive service for desktop and mobile users will have you finding your cloud-stored files much more easily. Once the update has rolled out to all, in the search bar, you will have the ability to select from a variety of file types which will act as a filter for you. If you are looking for a specific PDF, search only through “PDFs.” If you need a picture from last year, search only through “photos and images.”
Google does not state these changes as an update for any particular app, but will more likely be a server-side change, however you can download the APK from below. With that in mind, all users should see these improvements over the next couple of days through their respective platform of choice.
