Disk Defrag can analyze all fragments on drives and show how fragmented the drives are before you defrag. There's nothing wrong with the built-in Windows disk defragmentation tool, at least nothing that Disk SpeedUp won't fix, first by dramatically speeding up the defragmentation process and second by optimizing the disk by moving large files to the end of the drive and other means.ĭisk Defrag is a totally free and extremely fast defragmentation tool developed by Glarysoft to analyze, defrag and optimize disks or a single file/folder for peak computer performance. When scheduling an automatic session, we could select defrag, optimize, or both. Under Settings, we could change the language, integrate the program with Windows startup and context menus, set defragmentation and optimization parameters, and add files to the Exclude List. We could check for updates, but there's no Help file, though the developer's Web site offered some information. The color-coded defrag map gave us a good visual indication of the state of our disks. We can't swear to their effectiveness other than to note that this tool is certainly fast. We could analyze, defrag, or optimize our selected disks or folders as well as pause or stop the operation.ĭisk SpeedUp claims 'smart' defragmentation methods that speed up and improve the process. We chose both hard disks and all three partitions. To the left, three prominent buttons let us choose Defrag Now, Auto Defrag, and Schedule options. In the middle was a standard defrag map, while at the bottom of the interface, Disk SpeedUp displayed tabs with our three partitions, each with individual graphs and data. The Defrag Show tab showed our two disk drives and their capacity, free space, status, and percentage of fragmentation. Like many system utilities, Disk SpeedUp has a colorful interface with large, clearly labeled buttons and tabs labeled Defrag Show and Settings. It offers manual and automatic defrag options as well as automatic shutdown after defragmenting finishes. Glaryutilities' Disk SpeedUp is a free standalone utility that analyzes, defragments, and optimizes your disk drives or individual folders.
