Er, yes, thanks for that, I think!
Richard, I agree I should upgrade but funds are a bit tight at present.
I was actually joking about the number of letters I am using. The bit about deleting and recreating a partition leads me on to the second part of my original question - how do I partition the drive?
Goates - I do run Zone Alarm so can copy that to a CD. Can you remember when you did your bit on a clean install of XP? I did a search but didn't find anything.
From what you both say, it's going to be a case of reformatting (and then re-loading everything) rather than doing something clever in DOS for Windows only.
That does lead to another question - if I have downloaded a program, say Zone Alarm, to the C drive, can I just copy what exists in C:Program Files and get everything I need to re-load and run it, or are bits hidden elsewhere? I seem to remember trying that with McAfee Anti Virus on to a Zip Disk and then not being able to re-install it from the Zip.
