Windows users have lots of choices when it comes to defragmentation software. We have covered a lot of tools in the past, to name a few: Defraggler, FragExt, Auslogics Disk Defrag, MyFrag or Ultra Defrag. Not to mention the first party Windows defragmentation program that ships withe very copy of Windows.

WinContig is another free file defragmentation tool. The portable software can be started directly without installation. Files and folders can be added to the defragmentation queue by clicking on the Add button at the top. Folders includes partitions on the system. A click on the Analyze button scans the selected folders and files, and displays a fragmentation report in the end.

All fragmented files and statistics are shown in the main window. Statistics include the total number of fragmented files and the number of files processed. There is also an error tab displaying errors in case any appear during the scan. The analysis was fast on the test system. The performance depends largely on the drive speed, size of the selected folder or drive and the number of files that are stored on it.

It is possible to select only specific items or all fragmented items for defragmentation. A click on Defragment opens a new prompt. Wincontig recommends to run a check disk and disk cleanup before running the defragmentation. The actual defragmentation process can take some time, depending on the fragmentation of the files on the disk.

Defragmentation profiles can be saved and loaded to avoid configuring the defragmentation every time the file defragmentation software is started. WinContig has options to exclude files from the process and to configure relevant tools like the disk checking and defragmentation mode.

WinContig is compatible with 32-bit and 64-bit versions and editions of the Microsoft Windows operating system. Interested users can download the latest version directly from the developer website.

Several options are added as start menu entries after installing the latest MyDefrag version on the computer system. This includes running an analysis of all connected hard drives, defragmenting all of them, running a fast optimize script or to optimize flash drives. The real strength of MyDefrag are the extensive command line parameters and scripting possibilities that make it possible to individualize the defragmentation process.

Quite a few graphical user interfaces have been created for JkDefrag in the past. It is very likely that at least some of these will be made available for MyDefrag as well. This will help inexperienced users and those that do not like working with the command line to make use of the full functionality of the file defragmentation software.

MyDefrag is available for 32-bit and 64-bit editions of Windows XP, Windows Vista, Windows Server 2003 and 2009 as well as Windows 2000.

The following article explains how to repair defragment in Windows Vista. It will also mention alternatives in case the repair does not succeed. The following error messages are symptomatic: “The Disk Defragmenter is not installed on your computer” or “Windows cannot connect to the Disk Defragmenter engine”. The suggest help topics do not help in this case.

The first thing that can be done is to register two dynamic link libraries (dlls) again. This can be done by opening a command prompt as an administrator and typing in the following commands:


regsvr32 dfrgsnap.dll
regsvr32 dfrgui.dll


You might need to switch to the system32 directory first in the command line using cd /windows/system32/.

The second option is to reinstall the defragment tool completely. Locate the file dfrg.inf in the /windows/inf/ directory. Right-click it and select Install from the menu.

Alternatives To The Windows Defragmenter:

There are two possible alternatives. You can try and start the Dos defragmenter by typing in defrag.exe or install a third party disk defragmentation tool like disk defrag.
