Speed Up Computer
A heavily fragmented hard drive may slow down a lot of things on a Windows computer. A disk defragmenter helps organize disk space on PC and improve overall performance.Extend HDD Lifespan
The platters and the reading/writing head can suffer from excessive wear when the drive stays heavily fragmented all the time. Defragmenting hard drive and consolidating free space reduces the load on your HDD, helping it last longer.Help Enjoy Smoother Gameplay
Game files can be quite large, which makes it harder for Windows to find enough room to save the entire file in one spot. Defragmenting game files lets you ensure better frame rendering speed and less freezing while playing.Ensure Faster Scans and Backups
When you defrag hard drive, any operations that require a lot of reading or writing go at a faster speed. That includes antivirus or other diagnostic scans, creating system restore points or backing up your personal files.Compatible with Windows 7, 8, 8.1, 10, 11.
Still Have Questions?
Auslogics Disk Defrag automatically detects whether your disk is an HDD or SSD and marks the type in the corresponding column of the Disk List table. This way, you don’t have to worry about looking up your PC properties and trying to find your drive characteristics on your own.
If Disk Defrag detects that all of your drives are SSD, it will not run regular defragmentation on them. If that’s the case on your PC, we recommend that you install Auslogics SSD Optimizer and use its special SSD-safe algorithms to maintain your drives.
To find out the fragmentation percentage on your computer drives and check whether defragmentation is in order at the moment, you need to analyze your hard drives. After downloading and installing Disk Defrag, before you launch defragmentation or optimization, select the drives and run disk analysis. The app will read disk information, show you a true picture of the disk’s current condition and recommend actions to take.
Auslogics Disk Defrag supports the following Windows versions:
- Windows 7 (32-bit and 64-bit)
- Windows 8 (32-bit and 64-bit)
- Windows 8.1 (32-bit and 64-bit)
- Windows 10 (32-bit and 64-bit)
- Windows 11
It does not support Windows 2000, 95, 98, 98SE, ME, XP, or Vista.
There are no Mac or Linux versions.
Yes, Auslogics Disk Defrag Free is absolutely free for home and commercial use. To get access to advanced functionality, you can purchase a license to upgrade to Disk Defrag Pro or get the full-service professional drive optimizer – Disk Defrag Ultimate.
Your SSD drive is safe no matter what Auslogics product you use on it. However, Auslogics Disk Defrag is a program that is made specifically for HDD drives. As such, it will detect your SSD drive and will not run defragmentation on it.
To boost the performance of your solid-state drive, you can download and use SSD Optimizer on it. The app offers safe SSD optimization algorithms that help extend your drive’s service life.
If you want to use both Disk Defrag and SSD Optimizer, save some money by purchasing them as the Disk Toolkit bundle.
If you have both HDD and SSD drives, Auslogics offers the Disk Toolkit bundle, specially designed for users with both drive types. This bundle includes the Disk Defrag and SSD Optimizer apps, comes at a special price and provides comprehensive optimization solutions for both HDDs and SSDs.
During defragmentation, scattered pieces of data belonging to one file are rewritten into one place. The process is no different than regular data writing that happens when you create or modify a file, so the risks of data loss are no different either. Defragmentation is a safe process that is quite effective at helping your computer read data faster, and Auslogics Disk Defrag is a safe tool that helps maximize these effects.
Disk Defrag has been helping users around the world improve hard drive performance since 2008. Auslogics’ proprietary technology has been tested and recommended by IT authorities, allowing Disk Defrag to be included in the Best Defragmenters lists multiple times. Safety has always been a priority for Auslogics’ developers, which is why the company’s software is often chosen by IT administrators for use in office environments.
With that said, regularly backing up important data on your PC is something you should make a priority regardless of what software you use for system maintenance.
The recommended defragmentation frequency depends on how actively you use your computer, and especially – how much data writing happens during this use. For very active users who tend to save a lot of files, running defragmentation about once a week should be good. If you aren’t a heavy PC user, you may have your hard drives defragmented once a month. For very light users, every two or even three months may be enough. With Auslogics Disk Defrag, you can set up defragmentation to run on a convenient schedule. The program will first analyze your HDD and will run defragmentation only if it is needed.
