Earlier this week Diskeeper was mentioned on this list and I decided to have a look at the lite version. I tried it first on my old Win 98Se machine and although both partitions were in reasonably good health I let it defrag and it did so very quickly. I then turned to my Toshiba laptop (XP Pro) and got the following report on the c partition - Total fragmented files = 753 Total excess fragments = 2,685 Average fragments per file = 1.10 Which was somewhat alarming. I now have to decide whether to let the Windows Defrag program do the job or to leave it to Diskeeper. Any suggestions? I always found with Win 98 and its own defragmenter that to get the partition containing the OS to defrag properly I needed to quit as many things as possible ? firewall, AV program and screen reader, but with Diskeeper I left everything running and it seme to work OK. Should anything need to be closed before attempting defragmentation of an XP system? Thanks in advance for any advice, Douglas . -- Douglas Harrison
