Detecting directories with "directory?" method

Question

I want to detects directories im my computers.but when I write below code , Ruby just give me "." and "..".

Dir.foreach("c:/windows") do |i|
   puts i if File.directory(i)
end

please help me. thanks

It listed the current directory . and the previous directory shortcuts .., but nothing else. Are you sure the system you're on is able to read the C:/ partition correctly? — ankit

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

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

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
=>

Are you sure? if -d i is not even valid Ruby.

not sure at all now as i've tried it. hmm, i'm almost certain i've used -f -e -d etc with files, but maybe i've been coding in perl

(previous comment was referring to earlier version of answer)

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.
