If I understand correctly what you need to do, this should work.

require 'fileutils'

file_name  ile.basename(file_path)
dir  ile.dirname(file_path)
Dir.foreach(dir) do |f|
  if f file_name or f '.' or f '..' then next
  elsif File.directory?(f) then FileUtils.rm_rf(f)	
  else FileUtils.rm( f )
  end
end

To test the script, you can replace FileUtils.rm_rf(f) and FileUtils.rm(f) respectively with

FileUtils.rm_rf( f, :noop true, :verbose true)

and 

FileUtils.rm( f, :noop true, :verbose true)

With those arguments, FileUtils.rm and FileUtils.rm_rf don't actually delete the files (or directories), but print the operation that would be performed on screen, so you can check whether everything works. For more information on this, look at the ri documentation for FileUtils and FileUtils.rm.

I hope this helps

Stefano
