My computer has finished the defragmentation process. Why does O&O Defrag still show a fragmentation degree of more than 0%?
The reason might be one or more fragmented files, which are locked during run-time. Thus O&O Defrag can not defragment this file.Running a boot-time defrag with O&O Defrag might solve this problem, as the file(s) are not locked before the system starts and O&O Defrag can Defragment these files, too.Another reason might be a lack of contiguous free space available on your hard disk partition. If the fragmented file is bigger than the biggest piece of continuous space available, it is physically not possible to defragment the fragments. You might try to consolidate as much free space as possible by using the SPACE method O&O Defrag offers.
