iDefrag is a disk defragmentor for Mac that is in charge of optimizing the location of files in a predetermined volume.
It consists of five different defragmentation algorithms that allow you to perform the process by following different patterns. The only one of them that can defragment a mounted volume answers to the name of Quick (online).
To use the rest of the algorithms in the boot volume, it is necessary to boot the computer from a different volume. The complete version of iDefrag includes a tool to generate a booting CD/DVD with which to perform this task.
A function denominated Thermal Monitoring supervises the disk temperature at all time. If it is too high, iDefrag will stop defragmentation until the device cools off.
