Mem-O-Safe

Note: If you are using one of the O&O AutoSense profiles, it is not possible to make any changes to the settings. If you would like make manual changes, however, it is first necessary that you create your own profile.

The "Mem-O-Safe" feature in O&O CleverCache reduces the risk of possible data loss in the event of a system crash. This reduction in risk is achieved by allowing users to manually set the assessment interval for the file cache in Windows.

Before your data is written to the hard disk, they are first written to the file cache. The rationale behind this design is efficiency. Because the constant writing of small amounts of data to disk would not be an efficient use of time, this system was developed to optimize the process and overall performance. For this reason, Windows saves data to disk in intervals, so that the system can economize on the amount of data saved at once.

This interval, although defined by Windows, is not set in stone. It is determined according to a number of factors: the size of the file cache, the system speed, and results of the last write process. Generally, this interval is anywhere between 4 and 15 seconds.

If a system crash happens to fall between those intervals (e.g. program error, accidental shutdown, or power outage), data stored in the file cache is lost forever.

If you would like to increase the frequency by which data is written from the buffer to the hard disk, you will need to reduce the size of the update interval. The minimum interval length is 50 milliseconds.

Important: If you set the interval value to low (less than a second), you will be instructing the computer to save data to disk with a very high frequency. On the other hand, should this value be set too high, system performance will increase. However, along with higher performance, the risk of data loss in the event of a system crash also increases.
