Today, Google has introduced “app data folders” which are protected and can’t be seen by users within their Drive account. Other apps can’t see the files either, so there is now an added layer of security to fight off bad actors who build apps to swipe information or do other damage.
This is an interesting move which adds more iCloud-like functionality for Google Drive users. Rather than choosing between a Dropbox-like service and an iCloud-like service, Google seems to have gone down both routes, fitting them into the same product. I wonder if Google will eventually usurp Apple’s efforts to build a robust developer infrastructure. It should be noted that Google have yet to attempt the complex database syncing that Apple has had trouble with so far.
