There are times when we feel if we had this or that document. I faced this a lot and put my data on cloud, as they say it. My first space was mail provider which have lot of space (Google Gmail was choice then). Due to limitation, I moved to AjaXplorer (now called Pydio), because I had space available with my host and kept things in my control. They have an app too. With advent of services like DropBox & Box, it seemed I was just using up my hosting space.
