Google Drive is one of those apps that should be installed by default. I can't understand why the developers of Android haven't added the single best tool for accessing Google Drive accounts. For many users, this app is a necessity, especially when trying to work on the road. It provides access to photos, documents, videos, and any other files stored on your Google Drive account. You can also upload files, create files, share files, and access files shared with you by other Google Drive users.
