Over the past few years, I tested a variety of defrag software, some of which are among the big names in the industry. There is an analysis tool available in Ultimate Defrag which gives a numerical value of the degree to which a defrag job has optimized a hard drive. So far, and among a whole variety of software I gave a try, Ultra Defrag achieved the highest score after a full boot-time optimization (with file arrangement based on time of access in ascending order while keeping the other default settings), which was easily noticeable in the speed of file and application opening as well. The same excellent performance can be maintained by periodic quick optimizations after a full boot-time job, which can be scheduled as an automatic defrag.

I have used UltraDefrag for years. It has only improved with age.

UltraDefrag does everything I want it to do - and more. It is fast, reliable and stable I can only reecommend it.

It is going well. The problem is, on the MSFT issue, it should be improved to make it smaller and more usable. In all functions today, they are very good and functional.

Since it was open source has been the best defragmenter. It's also usable as a portable software. Now it's a commercial software, but nothing has changed.

UltraDefrag 10 works well on Windows 11 22H2 beta, also with Hyper-V Virtual Machines. I use SSD. Virtual Machines (Windows 10, Ubuntu) work more faster after the defragment of vhdx. I strongly recommend this useful software. Thank you so much for your products!
