By default, ArsClip is capable of remembering the last 15 items or text entries sent to the clipboard, but it can be configured to increase this amount.
ArsClip can also be configured so that it only remembers a specific kind of object, disregarding text fragments for example.
The program doesn't require installation and can be launched in portable mode, this means, from any external USB memory device. Even though it comes with an installer that will place it in a folder on the computer so that we can work with it whenever we want.
There are other tools that give the clipboard more options, but few of them are as simple and “invisible” as this one.
