iDefrag是一款用于Mac的磁盘碎片整理器，它将帮助你优化文件在不同分区中的位置。

它包含了5种磁盘碎片整理算法，帮助你完成进行整理工作。Quick（online）是唯一可以整理安装卷的算法。

想要在启动卷中使用其余算法，你必须从其它分区启动电脑。完整版的iDefrag能为用户生成一个启动光盘，帮助你完成碎片整理工作。

另一个名为Thermal Monitoring的工具将为你全程监测硬盘温度。如果温度过高，iDefrag会暂停整理工作直到温度恢复正常。

Every Mac user has noticed it; over time, your system slows down. This is particularly true in these days of constant security updates, as replacing operating system components not only increases file fragmentation, but also creates a more insidious problem—over time, the operating system itself ends up scattered all over your disk. This, of course, doesn’t show up as fragmentation—after all, the files themselves are probably contiguous—but nevertheless, it takes your machine longer to start up, it takes programs longer to start, and it takes longer to get your work done. iDefrag solves these problems and more, by defragmenting and optimizing your Mac’s filesystem.

System Requirements

Mac OS X 10.6 or later (including Mountain Lion), Intel microprocessor, 1GB RAM. Supports internal and external disks. To defragment your boot volume, you need to boot from a different volume (except for on-line defragmentation feature) or reboot into a special mode.

iDefrag can only defragment HFS and HFS+ volumes (i.e. Mac disks). It will not defragment FAT or NTFS volumes; if you are using these for compatibility with Windows systems, please use a Windows-based defragmenter.
