Subject: Re: FileTest.directory?( x ) weird behavior

The reason for the behaviour you're getting is that those filenames don't 
exist in the current working directory, only in the @userFilePath 
directory - that's why directory? is returning false.

Or you can change directory:

#...
Dir.chdir( @userFilePath ) do
  Dir.foreach (@userFilePath ) do |x|
#...
  end
end
#...
