Sony — SONY WALKMAN NWZ-S616F 4GB: Space getting wasted in spite of no uploading

Address:

Hyderabad, Andhra Pradesh

Plzzzz guys,

I'm using the so-called SONY WALKMAN NWZ-S616F for the past few months and recently stuck with a problem. The problem is like the space of the walkman is 4GB in which i not even uploaded a single album of songs but still the walkman displays that the empty space is only 350MB. So, around 3.6GB is unused. How to get rid of this problem??? Hope someone responds to this as soon as possible.

thank you
