Answer 1

In Ruby, there is no difference between the paths in Linux or Windows. The path should be using / regardless of environment. So, for using any path in Windows, replace all \ with /. File#join will work for both Windows and Linux. For example, in Windows:

Dir.pwd
=> "C/Documents and Settings/Users/prince"

File.open(Dir.pwd + "/Desktop/file.txt", "r")
=> #

File.open(File.join(Dir.pwd, "Desktop", "file.txt"), "r")
=> #

File.join(Dir.pwd, "Desktop", "file.txt")
=> "C/Documents and Settings/Users/prince/Desktop/file.txt"
