Clear or reduce the "recently used files" in the File menu

I am having trouble finding how to reduce or clear the recently used files in the File menu. In AutoCAD, there is an option to only list a limited number of recently used files (say 5) but I can not find a similar option in Draftsight. My machine is currently showing over 20 recently used files, which blocks half the screen when I choose the File menu. Alternatively, how do you clear the recently used file list?


Thanks,
