The instructions and explanations in this guide assume that you understand how to operate your Macintosh computer. You should, for example, know how to choose, select, launch, and drag by using your mouse. In addition, you should also understand how the desktop, windows, dialog boxes, buttons and file/folders work within the Macintosh environment. For more information about these items, please refer to your Macintosh User?s Guide.

About Disk Defrag
Intech’s Disk Defrag utility is designed to speed up your Macintosh’s access to files stored on your hard disks. To do this, the Disk Defrag utility identifies files on HFS+ formatted drives which are stored in more than one place on your drive and rewrites those files so that they form one continuous data stream. This process can dramatically reduce the number of data reads and writes to access your files, thereby significantly speeding up file access related functions. An additional and often overlooked side-benefit is file recoverability in the event of a catastrophic directory corruption of a disk volume. In the event that a disk volume becomes inaccessible due to corruption, a file recovery tool will have a much higher probability of recovering the entire contents of a file if it is physically located in a single place on the disk instead of occupying multiple scattered locations (i.e. fragments).

What is File Fragmentation?
File fragmentation occurs, typically, as a result of the continuous process of creating, deleting and modifying files. When a file is deleted, for example, it leaves a “hole” (i.e. unused space) in the disk at the place it used to occupy. If a new file is created that is larger than the deleted file whose “hole” the new file is filling, the file may be split in to multiple pieces and placed within the available “holes”. This file which now occupies more than one physical location on the disk is said to be “fragmented.” Each part of the file located on separate areas of the disk is called a file fragment. The number of fragments that a file can be broken into is virtually unlimited. It is typical for large files on heavily fragmented drives to be made up of several hundred fragments!
