In the past couple of months, I have been trying to find where all my drive C disk space went and I think I have found it. I originally took my computer to a computer store for my DVD rom drive to be replaced. Then it wouldn't boot up so I got that fixed. Then the store also said that the WiFi card was broken so I also got that replaced. Along the way the shop installed some software to check my system was ok. The below files I have descovered in defrage and there could be dozens more. I'm not sure if this is the remains of a virus, software or something the store might have done but would you know if it is safe to delete them. Because it is really taking up my 35GB harddrive. The main thing I need to know is are these files system files or are they program leftovers/files.
Also you can't just browse these files. You must type in the folders in the address bar. The way I found these files was by checking the defragment report since they couldn't be defraged.
