I'm not sure how JMimeMagic works, but if it's image formats you need to deal with, have a look at the ImageInfo class. It identifies a number of image formats based on the contents, not on the name or MIME type.

thanks for reply.
Well, it's most image and text. With images the JMimemagic is great, the problem is with txt, some times it fails.
