@Shlomy: Sadly it isn't possible to assign an SD card as the default location for all data, with the exception of photos and videos captured via the Camera app: Open the Camera app > Tap the cog Symbol > Storage > Change from 'Internal' to 'Memory Card'.
If you require the necessary steps to transfer files from your internal storage to your SD card then please confirm your current Android version and I will look into this for you (Settings > About Device > Android Version).
