so heres the deal, i had winxp home, backed up my data, and installed winxp pro. it works good, but i still have data from home left in my computer, like program files, and other stuff. how do i get rid of that. my hard drive is 80 gb, and i have 61.2gb out of 74.6(i think thats what it is) left on my computer. arent i suppose to have 74.6 gb in stead of 61.2. i thought that the installation would delete everything and start from scratch. so i installed it again, now i have 2 winxp pro on my computer. how do i fix my mistake. is there a way to reformate or delete the partition to create a new one. if theres anymore info that you would like to know feel free to speak. well any answer is appreciated.
