Beyond ordinary file defragmentation it offers quick and full optimisation passes that reorder files on the disk, defragmentation of individual files and folders, and filters that select files by size, fragment count, name or path, with an optional time limit for scheduled runs. Its signature feature is the boot-time scan, which runs before Windows has fully loaded so it can process files that are normally locked, including the MFT, page file and registry hives. This listing is the free open-source line's final release, version 7.1.4 for 64-bit Windows, published on the project's official SourceForge page. ## Installation 1. **Download the 7.1.4 amd64 installer** — Get ultradefrag-7.1.4.bin.amd64.exe (about 2.4 MB) from the stable-release folder of the official SourceForge project. This is the free open-source build, not the paid edition sold on the vendor's website. 2. **Run the setup wizard** — Double-click the installer, choose your language and components (GUI, console and boot-time modules) and complete setup. Administrator rights are required because the boot-time component integrates with Windows startup. 3. **Analyse, then defragment or optimise** — Open UltraDefrag, select a hard drive volume and run an analysis first. Choose Defragment for a light pass, one of the optimisation modes for a full reorder, or enable the boot-time scan and reboot to process locked system files. ## Editorial verdict UltraDefrag has a split identity, and this page will not pretend otherwise. The free, open-source program ended at version 7.1.4, released in 2020 and still served from the project's official SourceForge page; that is the build listed here, complete and unrestricted. The vendor's own website, ultradefrag.net, now sells a separate commercial edition that has reached version 16, with a modern interface and continued development, but it is paid, closed software and a different product line. If a site tells you the free UltraDefrag is at version 16, it is mixing the two up, and you will not find a free 16 anywhere official. Taken on its own terms, 7.1.4 remains a genuinely capable HDD defragmenter: the boot-time mode still does something Windows' built-in optimiser handles less directly, the filters and time limits suit scheduled maintenance, and there are no adverts or upsells anywhere in it. Its limits are about the era it belongs to. Development stopped in 2020, the interface is dated, and on any SSD or NVMe drive, which is most PCs sold in recent years, defragmentation brings no speed benefit at all and only adds write wear. Keep it for spinning disks and older Windows systems, where it is excellent and free; skip it entirely for solid-state storage. ### Strengths - Boot-time defragmentation processes files that are locked while Windows is running, including the MFT, page file and registry hives. - It offers quick and full optimisation modes plus defragmentation of single files or folders, not just whole volumes. - Filters by file size, fragment count, name and path, together with an execution time limit, make scheduled maintenance runs practical. - This 7.1.4 build is completely free and open source, with no adverts, bundles or feature-locked paid tier inside the program. - The installer is only about 2.4 MB and includes graphical, console and boot-time components for GUI or scripted use. ### Trade-offs - The free open-source line is unmaintained since version 7.1.4 in 2020, so there are no Windows 11-era fixes or interface updates. - Defragmenting an SSD or NVMe drive gives no performance benefit and adds unnecessary write wear, making the tool pointless on most modern PCs. - The split with the paid version 16 sold on the vendor's website confuses many users into expecting free updates that do not exist. ## FAQ **Is UltraDefrag for Windows PC free and open source?** Yes. UltraDefrag for Windows PC is completely free and open-source software. You can download and use it at no cost, and its source code is publicly available. **Why should you never defrag an SSD?** SSDs have no moving heads, so file fragmentation does not slow them down the way it does a spinning disk — and a defragmentation pass only adds unnecessary write wear. UltraDefrag is built for traditional hard drives, which is where defragmenting still pays off. **Does Windows 11 need defragging?** Only if it still has a traditional hard drive. Windows runs its own automatic optimisation on a schedule, which defragments HDDs and services SSDs differently, so most users need nothing extra. A dedicated tool like UltraDefrag earns its place when you want control — individual files and folders, filters, and a boot-time scan of files Windows normally keeps locked. **What is the best defrag tool for Windows 11?** UltraDefrag is a capable free, open-source option for hard drives: quick and full optimisation passes, defragmentation of single files or folders, filters by size, fragment count, name or path, and a signature boot-time scan that can process the MFT, page file and registry hives. The version listed here, 7.1.4, is the final release of the free open-source line. **Does defragging a hard drive make it faster?** On a traditional hard drive, yes — heavily fragmented files force the drive's heads to jump around to read them, and defragmenting pulls the pieces back together so reads become sequential again. On an SSD there is no such penalty, so defragging gains nothing. **How often should you run a disk defragmenter?** For a typical home hard drive, checking every month or two is plenty, and Windows' built-in automatic optimisation already covers most people. Run a manual pass with a tool like UltraDefrag when a drive feels slow or shows high fragmentation, and use its optional time limit if you schedule longer full optimisations. --- Source: https://filecobra.com/app/ultradefrag-pc/ · Mirrored from the publisher's own release channel by FileCobra.
