Help Can't Browse internal memory

[Mrcapo]

Sure hope some clever folk can help me here. I keep getting low storage error on my phone and indeed I have only 14MB left. Problem is I don't have too many apps so I want to have a nosey round to see whats taking up all my memory. For seem reason I can't find a way to browse my INTERNAL memory. External is no problem but I have tried debugging mode, no joy and Kies tells me internal browsing is not supported on this model.

Any ideas please kind people??
