Performance losses on workstations, home PCs, and server systems are not always caused by hardware. Inefficient use of available resources is often a key reason for noticeable slowdowns. O&O CleverCache optimizes file cache management and significantly improves your system’s performance. This allows you to avoid costly hardware upgrades or replacements, all with just a few clicks.

If you use your computer for several hours a day, you may notice a gradual decrease in responsiveness over time. After a restart, the system runs much faster again. This is because the file cache is cleared and reset during every reboot. O&O CleverCache performs this process while the system is running, eliminating the need for restarts while maintaining maximum performance at all times.

Reduce file cache for minimized applications

Many Windows users run multiple programs simultaneously during a session and minimize them to the taskbar for later use, especially office applications. Even when minimized, these programs continue to consume memory and may occupy file cache. O&O CleverCache significantly reduces file cache usage, increasing the amount of available memory. This results in noticeably faster response times for active applications.

Advanced profile management

The advanced profile management provides predefined profiles that simplify working with the software. You can also create your own profiles with custom settings. This allows you to load specific cache configurations for different use cases, such as video editing or gaming, exactly when needed.

O&O Mem-O-Safe: Control file cache update intervals

In Windows, data is not written to disk immediately. Instead, the system waits for additional data before performing a write operation. Normally, you cannot control this interval between cache updates. O&O CleverCache gives you full control over this behavior, helping to minimize or even prevent data loss in the event of system crashes, hardware failures, or power outages.
