O&O Defrag 2000 is a freeware Windows defragmentation tool. It is completely integrated into the Microsoft Management Console as a snap-in and can be used to replace the standard Windows 2000/XP defragmentation software.
Partitions can be analyzed and manually defragmented with the SPACE defragmentation function. You have now the possibility of showing clusters in the "faded" mode: the clusters are displayed in a brighter or darker color according to how full they are and their content. With the Cluster Inspector you can view the cluster contents and display fragmented files.
