PageDefrag 2.21

Windows NT/2000/XP does not allow you to defragment files that are opened with exclusive access mode.
This means that normal programs can not view the state of fragmentation of the paging file or Windows registry, let alone are not large to make a defragmentation of these components of the operating system.

PageDefrag uses advanced technology to allow what other programs fail to realize: being able to view the status of fragmentation of the paging file and registry can then possibly start defragmentation in order to improve performance global operating system.

PageDefrag work correctly in Windows NT 4.0, Windows 2000 and Windows XP.

Diskeeper Lite 3.0

Diskeeper Lite is a software that allows you to defragment your hard drive (entire drive or individual partitions). This is the abridged version derived from "Diskeeper", the full product, intended for use "professional".

The Lite version is still able to analyze the state of fragmentation of data stored on hard disk and allows you to perform the defragmentation manually on a single disc at a time.

However, this is an excellent solution able to put aside the defragmentation utility included in Windows.
