(See the best response by Nadrew.)
So on overwriting should I just delete a savefile and create a new one to update it or is there any trick to delete the dierectories without deleting the actual file?? and what is prefered??

You could just do

F.dir.Remove("/")


But the real question is, why? When you save data it will automatically overwrite any existing data in the same spot.
Because sometimes there are more data to be stored and other times less data so if I store 50 vars and then save again and 40 need saving I will have to find those 10 manually so I prefer delete all and save again.
Also IIRC since a var that doesn't deviate from its default will never save, old data could potentially be preserved in the savefile.
