Epubs fail to open on JB v35m - Answer found

This message was edited 1 time. Last update was at 08/21/2010 20:58:40

I just updated my Jetbook from 34c (installed by factory) to 35m (downloaded from Ectaco website).

My txt files and pdf files can still be read, but every epub gets "Failed to open file!" message.

My epubs are from a variety of sources. None of them have drm. All these epubs did open before.

Answer found: I was using the naming convention "last, first#title" for all my books. This still works for the txt and pdf files, but NO LONGER WORKS for the epubs. I have renamed each file. Setting the name to "last, first_title" works for epubs.

I've updated the post in case someone else has the same problem.

Hey,

Glad to see everything worked out! I'm still learning myself about naming of the files so it is always nice to see someone with a solution!

I'm a little confused by this. I thought Jetbook didn't much care what a file was named. That is one of it's greatest points; one can name a series of books 1_bookwhatever, , 2_bookwhatever, 3_bookwhatever, and put them all in a folder named Authorwhatever. Could it be a character you have in your listings that Jetbook is not liking? I read of that on another forum. I did not realize that epubs have tags like mp3s.
I would like to have this clarified before I upgrade to 35M. I have 35a installed and can use library books or books from Borders and do NOT want to have to rename all of my library.

Hey,

Maybe someone else can comment because i mention i am not too familiar with this topic. As always you can contact the technical support at 718-728-3605 or email [email protected]

If your current version is Ok and gives you all the features you need i would just recommend keeping it to avoid any confusion.

Hope this helps!

I like to use the same format for all my file names, so that the books will sort in author/title order. For a single author I may have some books in txt format, but others in pdf or epub.

On the JB, Ectaco had special handling for txt file names that did a pretty format in the book list if you named the file "author#title". The pretty format did not wo

What seems to have happened on 35m, is that the # character is not accepted as a valid character in an epub file name. I found that the _ (underscore) character was acceptable so I renamed my files and they now open. Playing around, I have also found that the - (hyphen) character is acceptable. Now I have a few epubs named "author-title" which looks a bit nicer in the book list.

Of course, the sorting isn't right anymore, but it is close enough.

The Jetbook does not require any particular file name convention. Each user can pick what works best for himself.

Here is the address of a free tool that makes changing a large number
of file names in a directory/folder quick and easy.

Another thing that I find makes such adjustments to my SD cards easy, is
the free "SyncToy 2.1" from Microsoft. You can keep a Master Copy of
your SD cards on a hard drive and use the tools and speed of your PC to
add and manage your ebook files in that Master Copy folder then just sync
with your SD card.

Luck;
