Yes we can tell you how to do this - but it's not a real good idea. It will mess with the recovery partition and could cause it not to work for you.
First, there's a difference between "memory" and "storage" - although both are expressed in "gigs". Memory refers to the amount of memory that your system can use for running programs - while storage refers to the size of your hard drives (and other storage devices like CD/DVD drives, thumb drives, etc)
So, it appears that you've got a Gateway PC. Usually the PC maker will install 1 physical hard drive and will partition it into 2 partitions (that, for some unknown reason they decided to also call "drives"). The C: partition on yours has 227 gigs of storage - and the D: partition has 5 gigs of storage.
So, the first step is to go to My Computer and right click on each of the partitions (drives) and select Properties. Note down the total size of the drives and the amount of free space left. (actually, it's the free space on the C: partition that is of concern here - but the other info will help to flesh out the picture of your drive structure)
Let us know how much room is left - and then we can suggest how best move the data.
