Microsoft has revised its SkyDrive cloud storage service offering at the same time it released an app for Windows Vista, 7 and 8 as well as Mac OS X Lion. Additional paid storage is now being offered, starting at Php440 per year for an additional 20 GB of storage. At the same time it paired down its free storage offering from 25 GB to 7 GB.
Existing users can retain their 25 GB of storage. Users who had 4 GB or more of files uploaded on SkyDrive as of April 1, 2012 will automatically retain their 25 GB of storage. Existing users of SkyDrive can keep their 25 GB of storage simply by simply availing of the free additional storage option in your SkyDrive account settings.
I am not sure how long existing users have to avail of the free additional 18 GB of storage, so I suggest you avail of it soon.
