A JavaScript file used by Google Pack reveals an interesting reference to GDrive. The file includes "localized information which is sent to translators". The product category for GDrive is "online file backup and storage" and there are two lines that describe the application (see the screenshot). If the description is accurate, we can conclude that GDrive will provide a software that could be included in Google Pack, you'll be able to store any kind of files and you'll be able to access them from your mobile phone, noted Brain Ussery. Also see this post, where CSS files evidents GDrive.
