This is the portable version of CleanMem - a tool designed to optimize the system memory when it is highly demanded. The mechanism is simple: the memory is cleared, and your computer's performance improves.
Since the app does not come with a setup pack, you can store CleanMem on a USB flash drive or similar storage device, save it to any computer and directly run its executable file. Therefore, the Windows Registry is not updated with new entries, and no leftover files can be found on the hard drive after program removal.
This kind of tool is highly recommended for users who have a small amount of RAM installed on their computer, making it difficult to simultaneously handle multiple processes.
The GUI is standard, but the program can be difficult to use by beginners (especially if they are not familiarized with scripts).
How does it work? In the Advanced Monitor section found in CleanMem Mini Monitor you can enable CleanMem to automatically run every given number of minutes, when memory usage surpasses a certain level (a similar option can also be enabled to automatically clean file cache).
If you access CleanMem Settings, you can enable or disable the system file cache clearance and log files creation, and select operating mode (all processes, ignore list, or only list).
In addition, you can install and edit a task scheduler, a feature that lets you create and manage common tasks, but also connect to another computer.
For example, if you want to create a basic task, you have to select the event or time that triggers it (e.g. daily, when a specific event is logged), as well the task you want it to perform (start a program, send an e-mail or display a message). But there are also more advanced and detailed options (when you create a task that's not basic).
The bottom line is that CleanMem is clearly an effective tool for clearing system memory, but also a thorough task scheduler.
