But then I can see the name However if I download them to the Nexus the names are just numbers and letters. So never know what they are to export to Aldiko, backup or anywhere.
So you are just backing up all the epub files? No cover etc?
The cover helps me know what is what faster lol
An epub file is actually a .zip archive. If (in Windows) you rename something.epub to something.zip then double click it you'll see it open just like a zip file. In the list of contents you'll see lots of .html files - you usually get one for each chapter - and also a file called cover.jpg that is the cover image.
So when you back up the epub you're actually backing up everything to do with the book - cover included.
When you import a book to Aldiko it extracts the cover, and also creates an info file called metadata.opf. However I think Aldiko only does this for convenience. Eveerything you need is in the .epub file so that's all you need to back up.
