I was a Diskeeper user for a few years until I heard about O&O Defragmenting. It supposedly was better, so I tried it and I use it right now. I saw that my pagefile was fragmented, so I enabled boot-time defragmentation to defrag all of the locked files. Every time, though, the last file won't defrag, and the possible reason is there isn't enough contiguous free space on my hard drive. In O&O, though, it shows a large amount of contiguous free space (22 Gbs free). Should I just use a different program, or is there a way I can get that last file done. Thanks.
