If you run complex games, simulations and applications, UltimateDefrag gives you the capability to place the files associated with these applications in the position on your hard drive that will give you the best performance possible. UltimateDefrag is the ultimate defragger and File Placement Optimizer. Defragging hard drives helps to restore your hard drive performance. File placement optimizing on the other hand, boosts your theoretical hard drive file access performance by up to 300% of manufacturers quoted averages (typical performance increase you'll experience is between 25 and 100%) by placing the files you want performance from onto the faster performing (outer tracks) areas of your hard drive. With UltimateDefrag - you can specify which individual files, programs or games you want the best performance from. The "Archive" function places all of your unused files out of the way and onto the slower performing areas of your hard drive.
Changes in UltimateDefrag Version 1.39 (17 January 2007)
* Added ability to concurrently select files/folders as well as access dates and extensions in High Performance and Archive seleciton screen. This vastly increases flexibility of file selection for Archive and High Performance. For example for Archive, you can select all files not accessed in the past 30 days, AND files with extension zip AND all files in System Volume Information and Windows Updates folders.
* While stalling was reduced on some systems, stalling may have been introduced on others. This has been corrected.
