This is how I am changing the directory path to the download folder.
Dir.chdir("C:/Users/abcd/Downloads/")
But this specific to a user. Is there is any way to make it more general?
Use home method for Dir
Dir.chdir(Dir.home + '/Downloads')
The "C:/Users/abcd/Downloads/" looks like the user directory for user abcd on windows. So I think this is a windows related question.
The Dir.home on my Windows-PC is U:/, not the user-directory.
But you can make use of ENV:
Dir.chdir(File.join(ENV['USERPROFILE'], 'Downloads'))
Just to be aware of: This changes the directory for the rest of your script. There is also a block-version of Dir.chdir.

I'm writing a simple console app, but instead of distributing it as a script (somefile.rb), I want it as a binary file, like an executable.
Any idea?
Embedded Ruby (or better mruby) into C or C++
Simple one file with script as text.
Here is example for mruby mruby.

I have a little question for you :)
I want to write log files from C:/Windows to C:/mylogs.txt with ms-dos commands. But I don't know any ms-dos commands. How can I do this. Please help me !
If you only pretend to copy the content of Windows logs that are stored in the root folder of C:\Windows, then you could use the Copy command as follows:
Copy /B "%WinDir%\*.log" "C:\mylogs.txt"

How can I navigate back one or multiple directories in Ruby?
For example:
users/luigi/test/folder/file.rb
If I'm in the folder directory and want my file.rb script to load a file from within the test directory, how can I do that?
Something like:
require /../required_file.rb
You can use require_relative
require_relative "../test/file.rb"
require_relative "../requred_file.rb"

I like to write some scripts for Winamp. How might I do this?
You can also use gen_scripting plugin which uses JSpript or VB which might be of use to you.
And a few words to the wise: Just add the plugin to the winamp plugins directory and remember to register it with regsvr32 from the command prompt. Scripting only works with Winamp running :)
