There are two mains ways of transferring data between your phone and your computer, one is by using blutooth (often not supported on many PC's hardware wise) and the other more common method is by using a lead that plugs into the usb socket and doubtless came with an installation disk for transferring files on and off your phone.
So my suggested action is to install the manufacturers software and then plug your phone into the lead, should be plain sailing, in most cases you simply drag and drop the files you want transferred.
