Hi, first of all sorry everybody for my english.
I have a nokia 6680 brand 3 (Italy) with installed a 512 mb memory card.
If I check Memory Card space there are:
- 490 mb total
- 43 mb is use
- 447 free space

but if I check details there is this situation:

3888 kb picture
3680 kb audio clip
4334 kb video clip
259 kb applications

3888+3680+4334+259 = about 12 mb
12 mb is very different to 43 mb!
thanks in advance.
with my best regards
