Free & Secured Online Drive

Hi, We would be saving lot and lot of data, documents pictures, videos and applications and our favorite games in our Hard disk. Even though we have large GigaBytes of Hard disk. It is tide some process to manage them all in a secured way and also there are chance of virus attack or Hard disk crash, etc.. so to get a solution for this we have a option of Online drives or virtual drives, on seeing free virtual drives which we get just for signing up in their site, we have given some limited space but we wont be getting assured that never they would close up their server or asks us to pay for storage or sometimes the server might be down. So to get a solution for this i have found a great place which is from Microsoft, leading software and OS maker ie., windows online drive.
We would be given 25Gb free space in our online drive, so we could save approximately 1000 Documents or 3000 songs or 10000 photos. Adding to this we can share online drive contents if we wish. When making them private we make those document for our private use. You can get these features at the following address
