This is a button for a useful little free program called "Text Mining Tool" that extracts text from PDF, DOC, RTF and HTML files. It has a command line version which means it works well with DOpus! The button processes the selected file(s) and outputs them in the current lister with a ".txt" extension added to the full original file name(s).
You can find the Text Mining Tool at www.text-mining-tool.com.
You don't need to install the tool, just run it from whatever subdirectory you put it in. Make sure to change the application path in the attached button, and you should be good to go!
