Huh? Wtf are you talking about? I said find the wuFTP package, not which one is most popular. Are you really that confused by Linux? You need to look at the leftside of your screen, not the right. Scroll down and on the left side of the screen look for the column titled: "Feature or package (data in brackets indicate the latest stable package". Go down that column and look for wuFTP included in any distro.
Btw, XP blows cuz it doesn't have memmaker.
