No matter which library software you use, the readers show the titles which can be found in the documents properties (and it doesn't matter if you change the titles of your books with a generic doc-program or with a library, like said in the first post). RTF-files is similar to txt. So there are differences in the properties of a file. Some have a dedicated title, some don't. Depending on this, the reader names the files.
The first time I added a pdf to my reader I really wondered that I couldn't find the book because I was looking for the filename I had used
