Hello to al the lovely people here,
I could realy use some advise.
I just received my very first Kindle. Because I used Sony before, I have a large collection of epubs. I will use my Sony on the side untill Amazon comes to the Netherlands and also has Dutch kindle-books from Dutch writers.
When I only had my Sony, I used Calibre to strip the DRM. Afterwards, I would remove the book from Calibre again and organised my de-drm-ed collection with good old Windows-explorer. I just drag and dropped the books into my Sony.
Anyways, I just put my entire collection in Calibre and converted everything into Mobi's. But what's next? Stripping the drm and converting formats is about everything I know of Calibre. I might want to organize my books with Calibre from now on though. But how does that work? Especially since every book will be in two formats. Can I sync my Kindle 4 2012 model with Calibre? What happens with the epubs when I do that?
I might have lots more questios, but let's just start with this.

Please bare with me

and thanks for the help
