How to access media files (photos and videos) on Samsung GT-I9082?
You can try Airdroid for fast file transfer from Android to PC over WiFi. Install it in your phone, turn on mobile hotspot and connect your PC to your local network. After that, Airdroid will give you an IP address. Just open it in your web browser of your PC, and you will get a nice file manager to access files.

If you have access to adb shell, you can also use 'adb push/pull' commands to copy files to/from your Android.
