Review Auslogics Disk Defrag – a free defragmenter for Windows 7

The free defragmenter Auslogics Disk Defrag is positioned by developers as a fast and reliable solution for eliminating file fragmentation, able to compete with the Windows system defragmenter. In this review, we look at the basic functionality of the application.

On the official page of the program Auslogics Disk Defrag developer declared the following features of this defragmenter:

  • Optimizes file system
  • Consolidates free space
  • Works in automatic mode
  • Equipped with a planner
  • Defragment individual files
  • Works with disks of any size

Due to the fact that Disk Defrag is considered by the developer, primarily as a replacement for the built-in defragmenter, we decided to compare its functionality with the utility utility integrated in Windows 7 by default.

Built-in defragmenter Windows has the ability to work according to a predetermined schedule and supports hard drives of any size. Unfortunately, the official Microsoft reference materials do not say anything about optimizing and consolidating free space with a standard utility.

Additional advantages of Disk Defrag, in relation to the standard utility, include the ability to configure the computer to shut down after the defragmentation has ended and a very convenient selective defragmentation function for a specific folder or file on the hard disk. This can be useful, for example, after installing a large application or game. Defragmenting the folder with program files immediately after installation may significantly affect the launch time of the application in the future.

Disk Defrag Interface

The appearance of the utility is simple and concise. It differs from the Windows defragmenter, first of all, by the visual presentation of basic information. Additional settings and functions of the program are concentrated in the tabs “Action” and “Settings”.

When using Disk Defrag, you quickly understand how the application developer compensates for its free of charge. Wherever possible, links to the paid software package Auslogics BoostSpeed ​​5, which you can find an overview of, follow the link provided. For example, the tab with the intriguing title “System Health” contains three counters – Files, Registry and Protection. When you open the tab, they immediately begin to count the number of problems found in the system. When you click on the “Details” button, we go straight to the advertising page Auslogics BoostSpeed ​​5.

Links to paid programs Auslogics can be found in the “Advanced” tab. In general, advertising is built into the interface of the program rather intrusively and does not interfere at all with the work with the application.

Defragmentation

To test the program, we used a laptop with a 250 GB hard disk, which was not defragmented for a long time. After analyzing the file system structure, Disk Defrag estimated the degree of fragmentation at 26%. Taking advantage of the ability to automatically shut down the computer after the completion of work, we left the laptop with a running program for the night.

Auslogics Disk Defrag – defragmentation process

In the morning, turning on the laptop and analyzing the disk for the presence of fragmented files, we saw the following picture.

Despite the blotches of fragmented files marked in red, the program determined the fragmentation percentage to be zero. We checked this data in the standard Windows 7 defragmenter – and he fully confirmed them. With the help of another popular Defraggler utility, we found that there are still 779 disconnected files on the hard disk, with a total volume of 380 MB.

After repeated defragmentation, which took only two minutes, the number of fragmented files was reduced to four and the disk, finally, was completely “fired”. Why did Disk Defrag not defragment all the files at once?

The solution to this situation was found almost immediately. We restarted the laptop and, once again checking it with Defraggler, we again found more than 600 fragmented files. Apparently, they are “generated” by Windows 7 itself, in the process of shutting down and turning on the computer.

Results

Auslogics Disk Defrag as a whole is a fairly convenient and high-quality program that does an excellent job with its main function – defragmentation of the file system.

The functionality of the program does not amaze the imagination and stands out only against the background of the standard Windows defragmenter. On the other hand, it’s understandable, the developer is actively promoting his multifunctional complex Auslogics BoostSpeed ​​5, which, incidentally, also includes Disk Defrag.
