O&O CleverCache v6 Professional is a unique tool that optimizes the File Cache Management for Windows NT, 2000 and 2003 and Windows XP.

All this is achieved without the need for additional software or any reduction in your system's stability. You simply install O&O CleverCache V6 and you’re ready to go – no need to reboot. It automatically recognizes your configuration, and within 5 minutes you can unlock the hidden resources on your Windows system! The more the file cache grows, the less memory is available for running applications. The result is a significant decrease in performance as requests for memory lead to the so-called "swapping" of memory. This occurs when unused memory segments are paged out to the hard disk's paging file. Because hard disk access is slow relative to Memory, loss of performance is inevitable. O&O CleverCache V6.0 Professional Edition is optimized to meet the day-to-day needs of individual users. The software is optimized to run on Windows NT4 Workstation, Windows 2000 Professional, Windows XP Home Edition, and Windows XP Professional.
