Smart Defrag is a powerful disk defragmenter with a fast engine and an easy to use interface. It's freeware for personal and business use. Like all defrag utilities, this requires admin privileges to run. It's been specially designed for modern, large hard drives, so it eliminates long waiting time. Smart Defrag doesn't just use simple defragmentation. It also streamlines your file system, places the frequently used files and directories into the fastest area of the disk, enabling your computer to run at top speed with the most stability. Its intuitive interface makes Smart Defrag the ideal utility for complete computer novice. Note that boot time defrag is not supported with the portable version and should not be used.
