Google Drive is a cloud based online file storage facility and a Google integrated file organizer, viewer and editor. You can store up to 15GB free space for all your photos, docs, projects etc. More importantly, you will never have to worry about backup and you can access your files from any computer and device. Additionally, you can make files available offline as well. The cloud advantage is that you can share your largest files easily without the need to attach. Drive is fully integrated with Google products and you can open most file formats directly in Drive. One powerful feature is that you can search any keyword within your file storage and Drive will return any docs, images or sketches that are related to that term.
