Short answer: The question doesn't entirely make sense. Long answer: What kind of files? DRM in documents, audio files, and video files all look and work very differently, and they're just the barest tip of the iceberg. It'd be pretty easy to write something that told you a .AAC file was protected by Apple's FairPlay, or tell you if a .PDF was encrypted... but something general purpose is probably far out of reach. Even the definition of DRM is very vague. You could say a password-protected .zip file or Word document is DRM-protected.
