Hi Sue, That is true. I will admit that sometimes, I have thought of splitting some files, just because I like to delete as a go along, and sometimes, I go the wrong way. Here is one way I sometimes do it. I have a braille display, as well, and this works for me. I put my file into a text editor. I search for a number, 301, for example. In the editor, I write cja. I go one line up, and hit the End key. I then save that as a block and give it a name. If you are reading a book on the history of Islam, for example, just call it something like islam1.brf. I use that example because there is a huge book on that subject.
