Okay, so basically awhile ago, my dad reformatted the computer. However, being the technological genius that he is, he didnt overwrite D drive, which is the largest drive i have, and instead installed windows on C drive. I haven't really cared until now, because it wasn't until recently that I started to realise that there was little space left on C drive. I was wondering if there was some way to transfer some of the space from D drive, onto C, and if it were possible to delete the D:\WINDOWS, and anything else that is also on D, that is already on C, without anything going wrong. Any help would be greatly appreciated. Thanks.
