Try ES File Explorer on your tablet.
I use it to transfer back and forth to my phone via Bluetooth.
The PC must have appropriate Bluetooth client software and of course a Bluetooth adapter.
I use Bluesoleil software on my PC.
There are some nice WiFi options for transferring files back and forth too, if both devices are connected to the same LAN.
I use Filezilla on my laptop and Wifi File Transfer on my GT-P3113.
