can u add partition

as one of our friend said that we can change the partition by a software called "partition magic" . we have other softwares too to change the partition.

You may try partition magic, I could change your partition to almost all kind type of partition, and It could also change your partition without formating first, example, your current drive c: still has 100 gigabytes free, you could split those 100 gigabytes to 50 each lively, without any format before, give it a try, but don't forget to back your important data first before trying.
