Hi Davey,
I discovered something at the weekend I should have realised years ago. This (my home) PC is shared by myself and my partner. When I had deleted temporary internet pages in the past, I had (wrongly) assumed that I was deleting them 'overall' the whole PC as it were. However, I now realise that my partners pages are stored in a separate sub-directory under her 'Documents and Settings', so I've now got a further cool 1.5GB back which means that 16% of my hard disk is now free (a 300% improvement on 6 days ago!!). Maybe you should put something on your help files to remind stupid folk like me that, if the PC is shared, each sharer should run CCleaner?
Prior to the above 'discovery', I had pretty much defragged all my 50-100MB files that weren't system or log files (not that many in this category actually), as far as they would defrag that is. However, now I've got more space back, they seem to be able to defrag further, so I've some more work to do. Will try and do this over the next day or two and then come back to you for what is amounting to the best tutorial I've ever had
