I think that what you mean is that you want to combine the C and E partitions -- you plainly can't move 3.4 GB of file into C.
Unfortunately, the partitioning capability of tools built in to Windows is quite limited, and can't do what you want. You need a real disk partition management application. I've never heard of "Partition Assistant Home" -- but that doesn't necessarily mean that it isn't a useful tool.
However, one of the following 3 applications should do the trick for you:
Easeus Partition Manager (free)
Paragon Partition Manager Personal ($9.95 for a 10-day trial)
Acronis Disk Director 11 Home ($45.95)
There are several others as well, but you can't go wrong with any of the above.
