Is a DLL 32 or 64 bit?

What are the necessary steps on a Windows system to figure out whether a DLL is 32 or 64 bits. Everyone knowing the file command on Linux, will look for a similar solution on Windows. When searching online for the problem, a lot of strange solutions come up … a Perl-Skript, install Visual Studio, etc.

I found the cheapest solution when browsing the ReactOS projects webpages: http://www.dependencywalker.com/. This is a very simple tool showing for each DLL symbol whether it has 64 or 32 bits. It is that simple you don’t even need to install Dependency Walker.
