Why Defragment Disks?

Hard disks are by far the slowest component in your computer. Therefore fragmented disks often become a bottleneck of the system performance. Besides causing slowdowns, fragmentation makes the disk drive heads move too much when reading files which leads to freeze-ups and system crashes. Auslogics Disk Defrag was designed to remedy system sluggishness and crashes caused by disk fragmentation. It will help you get the maximum performance out of your expensive hardware investments.

What’s new in Disk Defrag 3?

Auslogics Disk Defrag is not just a defragmenter any more, but a fully featured disk optimizer. And with all the advanced techniques of disk optimization it has, Disk Defrag 3 remains extremely compact and even easier to use!

Free space on a disk is often split into many small gaps between files. Windows fills these gaps with newly created or extended files. The more fragmented the free space is, the more fragmented new files will be. Disk Defrag merges free space into a large contiguous block. This technology dramatically slows further files fragmentation and speeds up disk access.

Commonly used by Windows, system files may be scattered all over the disk and intermixed with data files. Disk Defrag 3 arranges system files by defragmenting and moving them to the faster part of the disk. This minimizes the time needed for HDD to access system files improving overall computer performance.

Normally, NTFS file system reserves about 12.5% of the disk volume for the MFT records (a place where information about every file and directory is stored). However, when the rest of the disk space is getting low, the MFT Reserved Zone will be used for storing regular files. This may lead to MFT fragmentation.

Disk Defrag 3 replaces regular files from the MFT Reserved Zone into the rest of the disk space, allowing NTFS to allocate contiguous space for the MFT records and thus to prevent its fragmentation.

Disk Defrag CNet Video [+]

It is sometimes reasonable to defragment either one or several individual files instead of defragmenting an entire drive. Disk Defrag can save your time by defragmenting only those files that you’ve selected.

Running Disk Defrag on a regular basis ensures your disks stay defragmented. Use a wide range of its scheduler options to set the most suitable time span for disks defragmentation.

Defragmentation Explained

Fragmentation is caused by creating and deleting files and folders, installing new software, and downloading files from the Internet. Computers do not necessarily save an entire file or folder in a single space on a disk; they're saved in the first available space. After a large portion of a disk has been used, most of the subsequent files and folders are saved in pieces across the volume.

Fragmentation Maps [+]

When you delete files or folders, the empty spaces left behind are filled in randomly as you store new ones. This is how fragmentation occurs. The more fragmented the volume is, the slower the computer's file input and output performance will be.

Defragmentation is the process of rewriting non-contiguous parts of a file to contiguous sectors on a disk for the purpose of increasing data access and retrieval speeds. Because FAT and NTFS disks can deteriorate and become badly fragmented over time, defragmentation is vital for optimal system performance.

In June 1999 the ABR Corporation of Irvine, California, performed a fragmentation analysis and found that, out of 100 corporate offices that were not using a defragmenter, 50 percent of the respondents had server files with 2,000 to 10,000 fragments. In all cases the results were the same: Servers and workstations experienced a significant degradation in performance.

I have been a computer consultant since the late 1980's. Working on a host of machines from single PC home users, and complex business networks. I have been recommending and using Auslogics Defrag for the last two years for my clients and have found it to be the BEST defrag program on the market. I have compared multiple software packages and always come back to Auslogic. Especially for Vista users, in my opinion the Auslogics Defrag program simple works better than the default OS defrag program. I highly recommend this software and have not had any instances of incompatibility, which is extremely rare with any software. With over 1500 PC's that I service, this program is a crucial tool for my business. Highly recommend, and always, please support the software companies that make good software work great.

"Some people may miss the display XP put on as it moved sectors. More important, many people say Microsoft's defragmenter doesn't do a good enough job. Ausogics Disk Defrag is a free defragmenter. Its in-progress fragmentation map is better than XP's."
