RAMPro will empty out any free working space which was left behind from a process. Basically each program requires RAM to run, it takes some space and works with it. Sometimes a process doesn´t need that space any more but doesn´t empty it again. RAMPro will automatically empty out the freed space for you.

By default it will empty out all process every two seconds (this can´t be changed), but by clicking "Select process" you are able to select a process and empty out that one alone.

Minimizing RAMPro will send it to the tray, just click the icon once and it will return.
