I will shortly have to buy some up to date utilities for this sort of activity, defrag, uninstall and the like as I am expecting a new machine and my existing programs are getting long in the tooth. I would be grateful for any and all suggestions as to which suppliers are currently producing the best programs.
For working on disk partitions without loss of data, "Partition Magic" click here is hard to beat, For Defragging try "Diskeeper 7" click here For cleaning up your registry, Regcleaner is excellent click here
That should get you started, zaach, others will suggest other applications for you.
you will have to download TEMP CLEANER but unfortunately I am a traitor but its free and it could be in the download section of PC ADVISOR, click here or click here it gives u the option of removing all tmporary files including zip files but do check before u delete as some may be system files.
