Hi, thanks for the reply! Here's the part that doesn't seem to work, the application seems to stall and not read my files when I input them. What I'm doing is writing a document analysis utility, and I want to be able to take each chapter(each individual document) and be able to look at it in relation to the whole. You mentioned creating new files, but I don't know how much my Java app will be able to handle, overall I'll need to input almost 1 Mb of files. I'll eventually wittle them down to the important parts I need inside the application, but I need to be able to modify them inside the appllication first.
I hope this helps.
