Note to Softpedia users: We typically update this version a few days after the portable edition, because we prefer to wait for the ad-free version to be released, instead of listing the ad-supported edition of Defraggler. If you wish to be notified as soon as a new build is available, we advise you to follow that listing instead of this one. Thank you for understanding!
Defraggler is a small application that allows you to perform a defragmentation task on a drive or specific files.
The user interface may seem familiar if you used Windows' built-in utility or a similar software. You view a list of all available drives, including the removable ones, as well as the fragmentation level of a volume in Drive Map (after performing an analysis) and information about a selected drive.
So, you can process a volume (normally or quickly), check a drive for errors and defrag free space (to optionally allow fragmentation). You can also search for files or enable Boot Time Defrag (this option enables you to defrag files that are normally locked by Windows before it fully loads).
Furthermore, the program gives you the possibility you to schedule a defragmentation task (once or at a regular time interval) and it can be set to move large files to the end of the drive during the processing of an entire volume.
The Quick Defrag feature can be configured when it comes to the size and fragments size of files, and you have the option of excluding specific files and folders.
In addition, if Shell Extension is enabled, you can easily use Defraggler on any file, via context menu. Also, you can set the program to use more or less of your system resources, or shutdown the computer after it finishes a task.
The bottom line is that Defraggler does an excellent job at defragging a drive or a specific file and its online help file is very useful, especially for beginners. We strongly recommend this software.
