"No files showing up in
Recently I've started using RapidMiner 5. I want to process a set of .doc files. I've a collection of .doc and .txt files in a folder. So I've added "Process Documents from Files" operator. While adding the directory, I tried to see the files inside it. But there is no file showing up inside the directory. I've also tried with only .txt file in a directory. Still, there is no files showing up in the directory. Please guide me.
