Every computer user has noticed it; over time, your system slows down
Every computer 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 the potential for file fragmentation, but also creates a more insidious problemover time, the operating system itself ends up scattered all over your disk. This, of course, doesnt show up as fragmentationafter all, the files themselves are probably contiguousbut nevertheless, it takes your machine longer to start up, it takes programs longer to start, and above all, it takes longer to get your work done. iDefrag defragments and optimizes your disk for improved performance. Add in the size of some of the files in common use today, especially music, video, graphics and computer games, and even the best filesystem has trouble keeping things contiguous. Some people say that HFS+ is so good that you dont need to defragment. In a way, theyre rightHFS+ is pretty good at keeping small to medium sized files from getting fragmented it isnt particular good, however, at keeping large files or free space from fragmenting, a particular problem on the Mac because the swapfile must be contiguous on the disk, so you can actually run out of virtual memory long before you run out of disk space if your free space is fragmented. Another objectionthis time raised by Appleis that existing defragmentation tools may actually slow your machine down by moving files into or out of the Hot Band, defeating Panthers Adaptive Hot File Clustering code. As far as we know, iDefrag is the first defragmentation tool for the Mac that fully supports the Hot Zone, guaranteeing that this is not a problem. Even if you arent interested in defragmenting your hard disk, if you produce products on CD-ROM disks, iDefrag will be of use. Seek times on CD-ROM and DVD-ROM disks are many times slower than those of hard disk mechanisms, so fragmentation really hits performance, in some cases adding many minutes to read times. iDefrag can defragment disk images before they are burnt onto CD or DVD-ROM, optimizing access time and significantly reducing install or read times. And, unlike other products, iDefrag provides a wealth of information about your files, so you can see which ones are most fragmented and even look where they are on the disk. The screenshots on this page are from a perfectly normal 120GB hard disk, installed in a PowerMac G4 that is used for software development, wordprocessing and other everyday tasks (writing this web page, for instance). Look how fragmented it has become; most of that is actually down to one or two large fileslike /usr/bin/emacs, shown on the right, with 96 fragmentsbut there are a substantial number of less fragmented files, over 3,000 in fact..
