Hi Please help

Hi,

I am new to the forum.I was trying to get a software to increase the free space in my laptop harddrive.I found suitable software in Acronis disc partniotiner which supposedly will help to merge my C & D hard disks and give me a larger C drive with more space and a smaller D drive.I downloaded the software from geeks website but when trying it out realised it was atrial version and I can't really use it unless I buy it.Could anyone help me get the real software that I can use.

Thanks
