According to the Specifications for this model, the installed hard drive is tiny.
I believe the point of this kind of notebook is that most applications and data will be cloud based -- that means that it is not expected that you will store much data (files, documents, pictures) on the local system. In the case of a 32GB hard drive, you do not have a choice -- the drive capacity is minimal.
There is a rather neat (and free) tool you can use that will measure, compile, and report folder size data.
It is not terrible to have a computer that mostly uses the Cloud for applications and storing your data (OneCloud, for example). The management does require that you think about the kind of data you are ultimately "sharing with the world" in that there is some inherent risk in placing your data outside of your immediate control.
For the most part, we tend to ignore what we cannot control -- after all, the bank already has all your information, as does everyone with whom you have done business using your credit cards. If you use Social Media at all, everything you have ever posted is out there somewhere.
That said, consider what kinds of information you want to risk keeping in the Cloud storage, make your decisions, then relax and enjoy your computer.
