The most helpful feature is that it helps you to keep track of your personal files by assigning them different categories like work related documents, important business information, etc for easy retrieval whenever needed.The interface seems a bit outdated but this can be fixed by using a good web designing tool. Nothing as such. I would recommend this to anyone who needs to manage their files in an organized manner while keeping them safe from external threats. This is very useful especially if you are working with confidential documents and need to access them online. It's very convenient when you don't have any physical office space for storing files. I am able to use this service anywhere anytime when needed.
