Adding existing collection of ebooks to calibre
I'm reading all great stuff about Calibre on the Internet, so I wanted to give it a try.
However, at the moment I have a fairly large collection of ebooks (+5GB).
Mostly in .txt format, but some in .lit, .pdf, .html etc.
At the moment they are organized like:
A\Asimov, Isaac\I Robot.txt
Sometimes they are part of a series and then it can be:
A\Asimov, Isaac\Foundation Serie\1 Foundation.doc
So how do I enter these books into Calibre?
Taking into account the number of books, I would like to automate this as much as possible.
Should I re-arrange the folders before I import them into Calibre?
Should I import all folders at the same time, or author by author, or series by series?
All suggestions are welcome!
