^(Microsoft)随着Windows Vista^{(Windows Vista)}的发布，微软对Windows中的原生^(Windows)碎片整理实用程序^{(Defragmenting Utility)}进行了大幅改进，并在Windows 11/10/8/7中对其进行了进一步改进。碎片整理引擎和碎片的可管理性比Windows XP^{(Windows XP)}中的要好得多。

计算机的硬盘由存储数据的小碎片组成，随着时间的推移，当我们更改、删除或创建文件时，数据会变得碎片化并保存到不同的碎片中，尽管它看起来是同一个文件。碎片化可能会降低您的 Windows PC 的速度，因为计算机必须查看许多碎片才能加载单个文件。在此处阅读有关什么是文件碎片^{(what is file fragmentation)}以及它在Windows^(Windows)中如何发生的更多信息。磁盘^(Disk)碎片整理工具将数据统一起来，并尽可能将它们保存在相同的碎片中，以便计算机高效运行。

Windows 中的内置磁盘碎片整理程序现在作为低优先级任务在后台运行，而不会影响计算机的性能。它使用任务计划程序^{(Task Scheduler)}通过在机器空闲时运行来自动对硬盘进行碎片整理，因此不会影响Windows的性能。Windows现在将禁用SSD系统驱动器上的磁盘碎片整理，因为您不需要对固态驱动器进行碎片整理^{(State Drive)}。在Windows 11/10中，SSD 碎片整理^{(SSD Defragmentation)}默认启用。

阅读：^(Read:) 您需要对 SSD 进行碎片整理吗？

Windows Defragmenter仅对^{(Windows Defragmenter)}小于 64 MB^{(smaller than 64 MB)}的文件进行碎片整理，因为根据Microsoft的基准测试，这种大小的碎片已经由至少 16000 个连续的集群组成，对性能的影响可以忽略不计。这意味着游戏和大型媒体文件实际上保持原样！微软^(Microsoft)认为，对 64MB 或更大的碎片进行碎片整理需要大量的磁盘 I/O，这违背了最小化 I/O 的原则，并且给系统带来了更大的压力来寻找大的、连续的可用空间块。

如果您还想对大于 64 MB 的文件进行碎片整理，则需要使用某些其他碎片整理参数才能对各种大小的文件进行碎片整理。

Windows 10/8/7中使用碎片整理的最佳做法很简单——您无需执行任何操作。但是，如果您觉得您需要一个 3rd 方碎片整理工具来更好地碎片整理和/或什至轻松快速地对非常大的文件进行碎片整理，或者尽管尽了最大努力对内置的磁盘碎片整理实用程序进行故障排除，您仍然无法获得内置碎片整理工具工作，您可能想查看这 5 个免费的碎片整理软件。

Best Free Defragmentation Software for Windows 11/10

Microsoft has substantiallу improved the natіve Defragmenting Utility in Windows, wіth the release of Windоws Vistа, and further improved upon it in Wіndows 11/10/8/7. The defrag engіne and the manageabilitу of fragmentation is much better than what existed in Windows XP.

The computer’s hard disk is composed of small fragments in which the data is stored, over time as we change, delete or create files the data gets fragmented and is saved into different fragments though it appears to be the same file. Fragmentation can slow down your Windows PC because the computer will have to look into many fragments for loading up a single file. Read more here about what is file fragmentation and how does it occur in Windows. Disk defragmentation tools unite the data and try to possibly keep them in the same fragments so that the computer performs efficiently.

The inbuilt Disk Defragmenter in Windows now runs as a low-priority task in the background without affecting the performance of the computer. It uses the Task Scheduler to automatically keep the hard disk defragmented, by running when the machine is idle and therefore does not affect the performance of the Windows. Windows will now disable disk defragmentation on SSD system drives as you do not need to defrag a Solid State Drive. In Windows 11/10, SSD Defragmentation is enabled by default.

Read: Do you need to defrag SSD?

The Windows Defragmenter defragments files which are smaller than 64 MB only, for according to Microsoft’s benchmarks, fragments of this size, which already consist of at least 16000 contiguous clusters, have a negligible impact on performance. This means that games and large media files are effectively left as they are! Microsoft feels that to defrag to combine fragments that are 64MB or larger requires significant amounts of disk I/O, which is against the principle of minimizing I/O, and puts more pressure on the system to find large, contiguous blocks of free space.

If you still want to defrag files larger than 64 MB too, you need to use certain other defrag parameters to be able to defragment files of all sizes.

For most, the best practices for using defragmentation in Windows 10/8/7 are simple – you do not need to do anything. But if you feel that you need to have a 3rd party defrag tools to defrag better and/or even defrag very large files easily and quickly, or if in spite of doing your best to troubleshoot the inbuilt disk defrag utility, you are unable to get the inbuilt defrag tool working, you might want to check out these 5 free defragmenting software.

This free disk defragmenter for Windows, earlier known as JKDefrag, organizes files into zones, such as directories, Windows files, files used while booting, regular files, and rarely used files. Files that are often accessed are placed at the beginning of the hard disk while the files that are commonly used together are placed in proximity to each other. This organization, results in a dramatic speed increase, thereby allowing the computer to function efficiently.

Defraggler supports NTFS and FAT32 file systems. The portable application can be used as a replacement for the Windows inbuilt defragment tool since it is faster and offers some additional features too.

Simply select the volume you want to analyze, click on the volume name displayed on the interface and then click the ‘Analyze’ button. The program will analyze the disk volume and display results in seconds. The next step is to click the ‘Defrag’ button to initiate the defragmentation process.
