Will deleting partition and defragging increase performance in laptop?

[UberTiger]

I've got an laptop with Vista Home Premium on it.
It has 3 partitions, one is 10GB and says Healthy (EISA Configuration) - I think this is a restore partition?
One is the C: at 70GB.
The last is D: at 70GB.

This is how the laptop arrived from Acer. I use D: as a file dump currently.

If I move the files from D: to C: could I then delete D: and extend C:? And if so and I then defrag would that actually improve the performance or not. Or would doing a normal defrag without ammending the partitions be exactly the same?

Thanks.

Just defrag C:\. If you are on Windows 7 it should already defrag on a schedule, but you may need to set it up or amend it to suit when the laptop is running. Having it run at 3am if you never use it at 3am is no good, for example.

There is no reason to mess about merging partitions.
