The makers of CCleaner and Recuva have created a new software called Defraggler which is a defragmentation software for Microsoft Windows 2000 and higher. Defraggler introduces some new features that most - if not all - other defragmentation softwares are missing.

It is for instance possible to get a visual analysis of the fragmentation level of a folder or file. While it is nice to know, it would not make much sense if the software would not take advantage of this feature. Defraggler allows you to just defrag a folder or file instead of defragmenting the complete drive. This can be useful if you need a speed boost for a specific application if the application or data folder is highly fragmented and you do not have the time to defrag the whole drive.

This is of course considerably faster than defragmenting the whole hard drive and useful if you want to work with a certain application. As far as I can tell it is not faster or slower than any of the other defragmentation tools out there but as I said, the new feature makes it stick out from the rest.

When you first start Defraggler you are presented with a list of drives connected to the system. Each drive is listed with its name, drive letter, file system, capacity and whether it is an SSD or platter-based drive.

While you can click on the defrag button right away to run a regular or quick defrag on selected drives, it may make sense to first click on the analyze button to assess the fragmentation status. While it does not suggest a course of action based on that, it is certainly suggested to defragment a hard drive if the fragmentation status is high enough.

Defraggler warns if the drive is a Solid State Drive which usually should not be defragmented as it may reduce the life time of the drive due to the write operations needed to complete the process.

The program displays the status of individual files as well after the analysis which you can use defrag selected files only. A search is provided which you can use to display fragmented files that are larger or smaller than a selected value in Megabytes, or that match a pattern that you add to the search parameters.

Defraggler all in all is a useful file and drive defragmentation tool. The latest version of the program is fully compatible with all recent versions of the Microsoft Windows operating system.

    Automatic? I think the Freeware “IObit SmartDefrag” can do this.

    BTW: The portable Utility
    can this also – manually – when You place the JKdefrag.exe in Your “Send To” Folder
    and select any File or Folder and “Sendto” -> JKdefrag. ;)

    Is it automatic? I like automatic defraggers since there is no need to run the defragmenter manually or to set a schedule – the defragger handles everything transparently and without bothering me. It’s easier and more efficient than the old way of doing things.

    it works quite well.

    WinContig is a good alternative – a free standalone executable that can defrag individual files or folders. You can also load groups of files into profiles for future use.
