I need help in file Deletion.

I have a problem in file deletion. Each time I use [fileMgr removeItemAtPath: fileNamePath error:nil]; to delete, say for example word.app, it doesn't delete the bundle but rather only the contents. So after attempting to delete the file, I am left with the word icon with a void symbol above it (round icon with a slash often used in traffic signs) which is empty.What I need is to also remove Word.app. Need help please. Thanks, Benson
