Third-Party Tool Reports Fragmentation After Running Defrag.exe

Third-party disk defragmenter tools may report that your hard disk is fragmented after you run the Windows 98 Disk Defragmenter tool.

Disk Defragmenter optimizes programs by moving sections of executable files and supporting files into contiguous clusters on the hard disk. This can significantly decrease the time it takes to start programs. This optimization may actually result in single large executable files being fragmented on the drive as other related files are moved into intervening clusters. If you then run a third-party disk defragmenter tool, the tool may report that your drive is fragmented and advise you to defragment for improved performance.
