Read file headers using java

I am trying to read file headers using java, I want to get file type(image, audio whatever). I have tried many examples but nothing seems to work. I tried preon and no luck, can some one tell me how to read file headers using preon or some other Java apis thanks...

Solution

  • Use mime-util's MagicMimeMimeDetector:

    detector.getMimeTypes(file)
