How to see file list in Rails from any folder, outer Rails.root - Windows

I have rails application, I need see files in any folder. example I have application on c:\rails_app and in controller write this code:

@files = Dir.glob("Z:/*")

and don't see file entire directory in rails console work perfectly. I have question: How to see files from non rails directory? Thanks
--- after some answer
Problem not in use Dir class. Problem that Rails see only own root directory and i can`t change dir to other disk or folder in rails controller.

The equivalent of ls (list files) from the rails console is 

Dir.entries(Dir.pwd)

e.g.

Dir.entries(Dir.pwd)

# Returns this:

=> [".", "..", ".DS_Store", "app", ".ruby-version", "test", "bin", "config", "config.ru", 
 "storage", "README.md", "Rakefile", "public", ".gitignore", "package.json", "lib", "db",
 "Gemfile", "log", "Gemfile.lock", "init.R", ".git", "tmp", "vendor"]

As juanpastas mentions, this might be an escape problem. The underlying problem, however, is that a path is not a string! A path is a path(object) and could best be treated as such:

path = File.join("Z:", "*")
puts path
@files = Dir.glob(path)

Or, shorthand:

@files = Dir.glob(File.join("Z:", "*"))

Additionally, Rails (and other apps) have wrapped this Pathname in e.g. Rails.root, use like so:

@files = Rails.root.join("lib") #=> Z:\path\to\rails\app\lib.

You can use Dir#entries, Dir#glob or Dir#[] to get a listing in any folder.

Dir.entries('/Users/ccashwell/.vim/')
=> [".",
 "..",
 ".git",
 ".gitignore",
 ".gitmodules",
 ".netrwhist",
 "ackrc",
 "after",
 "autoload",
 "bundle",
 "init",
 "LICENSE",
 "README.md",
 "snippets",
 "syntax",
 "vimrc"]

Dir.glob('/Users/ccashwell/.vim/*')
=> ["/Users/ccashwell/.vim/ackrc",
 "/Users/ccashwell/.vim/after",
 "/Users/ccashwell/.vim/autoload",
 "/Users/ccashwell/.vim/bundle",
 "/Users/ccashwell/.vim/init",
 "/Users/ccashwell/.vim/LICENSE",
 "/Users/ccashwell/.vim/README.md",
 "/Users/ccashwell/.vim/snippets",
 "/Users/ccashwell/.vim/syntax",
 "/Users/ccashwell/.vim/vimrc"]

Dir['/Users/ccashwell/.vim/*']
=> ["/Users/ccashwell/.vim/ackrc",
 "/Users/ccashwell/.vim/after",
 "/Users/ccashwell/.vim/autoload",
 "/Users/ccashwell/.vim/bundle",
 "/Users/ccashwell/.vim/init",
 "/Users/ccashwell/.vim/LICENSE",
 "/Users/ccashwell/.vim/README.md",
 "/Users/ccashwell/.vim/snippets",
 "/Users/ccashwell/.vim/syntax",
 "/Users/ccashwell/.vim/vimrc"]

I think what can be happening to you is that \ escapes next character. Try:

@files = Dir.glob("Z:\\*")

or:

@files = Dir.glob("Z:/*")
