Hi, My Win Vista machine seems to add or delete up to 1Gb of data on a daily basis. I have two 50G hard drives and it is the C: drive (the main one for the PC) that is displaying this activity. I basically use the PC to check personal emails and little else, so I am surprised by the disk memory changes each day. Is there a way for me to see what files are changing or being added or deleted from the disk on a daily basis? I tried to see this with Windows Explorer, but it does not show any large files with recent edit dates. So, I am thinking that there must be a better way. Thanks for your help with this.
