Along with what others have said...
Realistically, it doesn't make very much sense to have data files on your C: partition, unless you are just using such to fill up space.
And always remember that Windows needs a certain amount of space for temp files, IE cache, virtual memory, etc.
OTOH, programs and the O/S need to be on that partition. Even though programs can be installed on a separate partition, my opinion is that programs and the O/S were meant to be conjoined and there's no real reason to set them up any other way.
All those pictures, movies, data files, and whatever that some put on the C: partition...really can quite easily go somewhere else.
I normally use 20GB C: partitions, with XP and programs using about half of that space (the other half is just there).
If you intend to make changing partition sizes a regular activity, you may want to look at a utility like Partition Magic.
