How to: Notepad Plus, turn off the setting of last opened files

Notepad plus is really a plus tool for developers like me, sometimes, I don’t want the tool list all the last opened files. By default , it will remember the last opened files and leave it there next time you open it. like a append only file , keep increasing , never get shrinked

To turn off this setting, there is no obvious setting like “disable last opened files”, but there is one option pretty unobvious.

Under [Setting] –> [Preferences..]->[MISC]

Also, there is another option to keep the editor only open last N files, like a fixed FIFO queue.
