pdfDX--PDF File Text Data Extractor. Have you ever tried to get text from a PDF File? The concept of the paper-less office is creating many more PDF Files. These Files are DIFFICULT, IF NOT IMPOSSIBLE to extract complete and accurate information effectively and efficiently. Many times today, when many large documents are presented, such as in Legal Discovery or Business Acquisitions and many more situations, all you receive is a CD, FULL OF HUGE PDF FILES. And, sometimes you're only given a short amount of time to peruse all this documentation. How do you do it? Some PDF Files won't even let you copy and paste text.
