It is also the part of the directory. To move up folder. So need a conditions in the each file of the directory to remove those two files.

Your code seems to work fine, except File.directory(i) should be File.directory?(i)

Dir.foreach("/mnt/tmp") do |i|
   puts i if File.directory?(i)
end

Dir.foreach returns only the filename (relative) , so it won't work. Build the absolute path or better try a simple:

Dir['c:/windows/*/']
