It looks like you're trying to remove all the files in the directory at 
once. Bear in mind that FileUtils.rm wants a _list_ of filenames, not a 
pattern to match. You can specify a list of filenames by accumulating 
them in an array and then using the splat operator:

filenames = whatever it takes to get all the filename in an array
FileUtils.rm(*filenames)
