To transfer from your phone to your PC, simply select the file you want in whatever application you’re using and choose the option to share it.
You’ll usually have the option to share in a number of ways.
For Windows 7, select the Start button, then select Devices and Printers.
Select Add a Device and wait until it discovers your phone, then select Next.
If you want to explore the contents of your phone or transfer a large number of files, this is probably a better option than Bluetooth.
