In my opinion, that is the wrong place to put it unless you fix the size of the swap file. If it is not fixed, then it is dynamic, and will constantly be shoving all your files around causing more fragmentation and bad optimization. If you must have it on your C: drive, then put it at the END so that changes do not shove everything else around.
I like a small dedicated partition . . . and the swap file doesn't need to be 1 gig for sure.
