I understand that is an incredibly stupid question but I thought I'd better check with the expects of this forum before I do anything too radical.
Basically, a year ago my XP pc destroyed itself and I had to go the repair shop. Afterwards the entire contents of my old drive C were in a folder called 'old' in the main C directory. A year on, I do not need any of the programs or documents in this file as I reinstalled everything and had my documents recovered separately. As I had lots of spare hd space back then, I just left the 'old' folder where it was. At the moment however, I am doing some spring cleaning and I could really use the 70gb of space the folder takes up. Is it safe to delete, or does the system still rely on some files within? Bear in mind the system was completely reset when I took it to the shop. I know I'm probably being neurotic but I don't want another dead computer.
It isn't. There is 'Documents and Settings.old' and 'Program Files.old' but the windows folder does not have this suffix. It's also in lower case, unlike the main windows folder in the main C directory.
