Windows 7: how too add more space to cdrive

ive got c drive with 37.2 gb and thats on disk 0
and ive got a f drive with 37.2gb and thats on disk 1

my question is how do i add the momory from drive f to c drive? is it possible even though they are not on the same disk?
ive tryed computer/ manage that didnt work when trying to extend volume and ive tryed partion wizard and that doesnt seem to work with merge or anything?

is there anything else i can do as when i install my programs the cdrive gets full..

How about going to the store and buy a disk made in the last 10 years? Then you get a lot of space.

You can't enlarge C to a larger size.

You can either buy another larger disc or delete things from your current disc.

Consider uninstalling programs you don't use.

You might try Disc Cleanup or CCleaner. They might gain you some space. But your real problem is having antique 40 GB drives to start with.
