Disk defagmenters do not always manage to defragment all individual files, especially when the files are multi-GB ones.
Windows defrag rarely can defrag large files in a single pass - because when Windows is running, many files are open and not able to be moved, defragmented or deleted - interfering with the consolidation of a large file that may be fragmented by the intercalation of active files.
A boot-time defragmenter will defrag all files usually because Windows has not loaded yet and the majority of files are not opened.
Puran Defrag is one such example and also can defragment individual files on demand from the right-click menu.
Individual file defragmenters are also available from Neosmart and are used in the EasyBCD utility for defragmenting ISO files and VHDs:
