title: What is the purpose of .dfm files in C++
body: <p>I have used C++ in Unix and I am aware of .h and .cpp files, but I have never worked on C++ builder and now I have got a project that contains .cpp, .h and .dfm files. So what is the the purpose of .dfm files and how do we use it?</p>
  
  <p>Thanks in advance.</p>
