PerfectDisk is the world's leading disk defragmentation and optimization utility, used by large enterprises, small businesses, and home consumers to maximize the performance and reliability of their laptops, desktops, servers, and virtual environments.

PerfectDisk Free Defrag will enable you to easily select and analyze the drives and as soon as the analysis is complete, you'll be able to optimize the disk and defragment partitions when necessary.

Every time you use your computer, even when it's brand new, the files on your PC or laptop will continuously become fragmented. This means that these files are split into millions of pieces, and this occurs even more so when you go to add, modify and delete them. So when you go to access a file - even just to read it - it will take much longer than necessary because Windows has to first find each piece of the file before you can even see it.

This makes using your computer, and doing everything you want, much slower than it should be. Fragmentation also leads to much slower boot times and will make applications run slow or even potentially cause them to "lock-up" or freeze. Defragging your computer puts the pieces of your files back together into a single piece - the way they should be.

A defragmented computer will boot quicker, files will be accessed faster, and your applications will not hang. A good disk defragger will not only defragment, but will also consolidate the free space on your drives into one large piece so when you create a new file, there will be enough free space to save that file in a single piece, rather than fragmenting right away. Defrag for a faster computer and a healthy PC.

Features:

Safety - Microsoft provides disk defragmenters with a safe way to defragment files online, while Windows is running. These defragmentation APIs are a part of the native Windows file systems and have been coded, tested and certified by Microsoft to ensure that no data loss or corruption occurs when a file is moved. The defragmentation APIs are fully synchronized with all file I/O and memory management functions of Windows. Microsoft’s defragmentation APIs even allow defragmenting files that are open and currently being modified. For safety reasons, PerfectDisk uses Microsoft’s defragmentation APIs. This ensures that peak system performance is maintained in a safe manner.

Large Drive Support - Large drives are common in today’s operating environments. Drives that range in size from 100 gigabytes to several terabytes can now be found. PerfectDisk is designed with the goal of being able to quickly and completely defragment large drives. PerfectDisk is able to completely defragment large drives 3 to 4 times faster than other defragmenters can - all while using minimal system resources.

Patented File Placement Strategy - PerfectDisk has a patented file placement strategy called SMARTPlacement that is designed to slow down the rate of refragmentation and to speed up future defragmentation passes. PerfectDisk accomplishes this via consolidation of free space and by identifying both rarely modified and recently modified files, and grouping them together. SMARTPlacement of files results in your drive maintaining its peak performance longer and reduces the need to frequently run defragmentation passes.

Scheduling Defragmentation - Using PerfectDisk, you can schedule defragmentation of your drives and leave the rest to PerfectDisk. PerfectDisk automatically starts defragmenting the drive at the scheduled date and time.
