I have read that some people do not think that it is necessary to defrag. well I disagree and think that the registry and the hard drive should be defragged on at least a monthly basis.
But what I am using, at the moment, seem to be getting slower and slower. I know there are recommendations on PCA but what I would prefer is for some of you readers what you have and use. I would, obniously, prefer free ones because I have found that when you purchase this sort of programme then you get offered an upgrade and they just then keep coming with very little being gained for all the extra cost involved. OK the free ones don't have all the bells and whistles, but many of these I think are just not wanted, when all I want the programme to do is to get the files into an order where they can be got from the drive in the shortest time possible. I would also like to be able to defrag external hard drives.
So if anyone could let me know what they use I would be very grateful.
You don't defrag the registry. You can run registry cleaners but most make little or no difference to pc performance. In the days of small hard drive its may have made a slight difference. Defragging the hard drive can be useful but it depends on OS. W7 has a good defragger built in. You must not de-frag SSD's.
