The different extensions mirror the different e-book formats.
Some of these have meta-data or headers that always or sometimes contains the title and author and if the JetBook Lite knows this it shows that information and otherwise shows the filename. Text, .txt of course is very plain hence the # trick of which Arthur_Conan_Doyle#The_Adventure_of_the_Dying_Dete ctive.txt
is an example.
Copying what I added to
https://wiki.mobileread.com/wiki/JetBook_Lite
The Jetbooks display the title and author of each book with a file naming convention of author_Name#Title_of_Book.txt for text file in order to list/sort the books by either author or title. The file name is shown in other cases where the JetBook cannot extract the title and author from the file headers.

Thus FB2 e-books have metadata title and author - see the preloaded free books and PDF e-books may have - the two pre-loaded do not but I have a bunch of free e-books from
http://www.bookdepository.co.uk/free
For these the data is present but the author is given as the person who generated the PDF and the title is often "Microsoft Word" followed by the ISBN-13 reference.

Some Mobi and ePub e-book may contain metadata title and author, but I have no examples yet.
