Instead of simply showing the fragmented files, it reports the extent of performance degradation on the disk. A group of horizontal bars in the Performance Map pane gives a graphic representation of the fragmentation of your disk volume. One of the most interesting aspects of the software is the Performance Map window. Additionally, it determines the optimum (fastest) read time potential for the disk. Secondly, it shows the time to read only the fragmented files. First, it shows the predicted time to read all the files on the disk. Each time you analyse or defragment a disk, Diskeeper calculates the read time of the disk in two ways. Indeed, in our tests we never noticed any performance hit when the software was running. Thankfully the software consumes negligible system resources, so in most cases will never need to be disabled. It also runs all the time, whether or not defragmentation is occurring. Remote installation can be a tremendous time saver for system administrators, especially on large networks, where you may have to install Diskeeper on hundreds of computers.ĭiskeeper starts automatically each time your computer is restarted. It can be installed simultaneously on multiple computers in a network, using either Diskeeper Administrator Edition, or Microsoft’s System Management Server (SMS). And because Diskeeper runs online, there’s no need to lock users off while a hard disk is being defragmented.ĭiskeeper is available in a variety of editions, ranging from Windows 95 through to Windows Server 2003 Datacenter Edition. The software can also be scheduled to run either invisibly as a background job or as a manual defragmenter, rearranging files and freeing space on a disk volume while you continue to work. Diskeeper cleans them up and keeps them that way, including drives with compressed, encrypted and sparse files on NTFS volumes. With Diskeeper, all the disks in a Windows operating system can be kept defragmented indefinitely. Either way it’s bad: excessive fragmentation can delay file access and file creations take longer because space for the file must be allocated in pieces rather than all at once. On a fragmented hard disk, pieces of individual files on a disk volume are scattered around the disk rather then contiguous also, free space on a disk volume consists of little pieces of space here and there rather than a few large areas. Although Windows comes with its own defrag utility (which was also developed by Executive Software), it requires a manual process to keep track of fragmentation levels and takes forever to run on large hard disks. It can also cause crashes, slowdowns, freeze-ups and even total system failures. Hard disk drive fragmentation is a major cause of performance bottlenecks.
