Auslogics Disk Defrag will speed up your computer by optimizing file system. It can defragment files, consolidate free space, and move system files to the faster part of the disk. With this disk defragmentation tool, you will get the maximum out of your hard drive performance. It is supplied with a powerful engine and smart algorithms that allow Disk Defrag to run much faster than similar tools. And with its comprehensive reports, you will always be aware of what has been done. The app features fast and safe defragmentation of the disk drives, optimization of clusters structure and file system for even better disk performance.

Disk defragmentation

Disk defragmentation

Auslogics Disk Defragmentation Features

Smart Defrag Algorithms: The program sports 4 algorithms for intelligent file placement, which are sure to cover whatever specific optimization needs you might have. Use the Optimize by Access Time method when you want to have faster access to frequently used files. In order to speed up your system loading and application startup, use the Optimize by Prefetch Layout algorithm. If you just want to reduce further file fragmentation, then choose Optimize by Change Time. And finally, the Optimize by Disk Zone algorithm allows you to manually specify which file types or even individual files should be written to the faster part of the disk.

Boot-time Defrag: Boot-time or offline defragmentation lets you defrag even the system files that are normally locked by Windows. Offline defrag runs on system startup, before the operating system loads, and allows you to streamline the following system files: MFT files, Paging file, Hibernation file, and Windows Registry files. Defragmenting system files will make your Windows more responsive, speed up system loading, and overall performance.

Algorithm for SSD Drives: The special SSD optimization algorithm greatly reduces the number of write operations during defragmentation, which prevents excessive wear and allows to extend of the disk’s lifespan. If you prefer not to include your SSD in defrags or optimization, you can set the SSD not to be displayed in the list of drives at all.

Disk Cleanup & Checkup: For faster and safer defragmentation, you can set the program to remove temporary files and check the disk for errors prior to defragmenting. This ensures that the program won’t have to waste your time processing junk files, as well as that there won’t be any data loss if the disk happens to have errors.

Defragmentation Wizard: With so many disk optimization algorithms and defrag options available, how do you choose the right one for your PC? Thanks to Defragmentation Wizard, it’s a matter of just a few simple clicks. All you have to do is specify what purpose you mostly use your computer for (home, office, gaming, or as a server), how often you work with various types of documents, and when your PC is on but is not in use. This information will help the program suggest optimization algorithms that will work to achieve optimal disk and system performance.

Advanced Scheduling Options: You can set the program to run precisely at the specified time, or alternatively, use Auto Disk Defragmentation mode, which enables the program to defragment and optimize your disks in real-time, making sure that file fragmentation is eliminated as soon as it occurs. And thanks to adjustable resource usage restrictions, any of the scheduled tasks won’t ever disturb you while you work or play on your computer.

Single File or Folder Defragmentation: Sometimes it makes more sense to defragment frequently used files only, instead of defragmenting the entire drive. It can save you time by defragmenting only the files you want. It allows you to defragment a single file, several files, or an entire folder. This option is useful when certain files need to be defragmented to speed up an application and there is no need to defragment the entire hard drive.

List of Fragmented Files: Disk Defrag Ultimate lists all fragmented files after performing disk analysis. Selecting a file from the list will highlight its fragments’ location on the cluster map. You can find the most fragmented files and their paths by sorting through the list. The list also lets you choose files to defragment and files to add to the ignore list. All you need to do is right-click on a file in the list and select the appropriate option.

Fragmentation Prevention: It allows you to specify the amount of free space to be left after certain files to ensure that these files have room to expand. This effectively prevents fragmentation by allowing new data to be written in the same location as the original file it’s being added to, instead of somewhere else on the drive.

Free Space Consolidation: Use the Free Space Consolidation algorithm to greatly slow down the process of file fragmentation. This optimization method merges free space on your disk into a large contiguous block, which makes it possible for new files to be written without fragmentation. Note that while consolidating free space, the program also defragments files, but you can disable defragmentation to make the consolidation process go faster.

Resource Management: It allows you to easily control the load on system resources produced by the defragmentation process. Restrict the use of system resources by the program when you are at your PC, or lift any restrictions to defrag your disks faster. There are 4 pre-defined resource usage profiles you can choose from. Alternatively, you can create your own profile with specific CPU and disk usage restrictions. You can also restrict the launching defragmentation process when a specified application is running or your laptop switches to battery power.

Performance Charts: You can easily track performance improvement and your system state through detailed reports and charts provided by the program. View the degree of file and free space fragmentation, size of the largest contiguous free space block available on your disk, and a number of files processed during each operation. All reports can be viewed, printed, and stored in a format convenient for you.

VSS-Compatible Algorithm: Equipped with algorithms designed specifically for Volume Shadow Copy Service (VSS)-enabled drives. It works to minimize the growth of the VSS storage area caused by file movement during defragmentation and reduces the chance of overwriting previous VSS snapshots. This eliminates the problem of free space shrinking during defrag, which users may experience with some other defragmenters.

Pros and Cons Of Auslogics Disk Defrag- Disk Defragmentation

Pros Cons
Easy to use Help is online only
