I just found this great site and registered. New to Calibre, and still learning.
I use Calibre to change the format of my purchased e books. Mostly from epub to azw3 and from azw3 to epub.
After I convert them with Calibre, I export them into my documents folder (in different subfolders).
I notice that Calibre also moves a copy of the original format. All I want is 3 files within the subfolder.
For instance, I want to have only epub document, jpg and opf.
it is very time consuming to go to each subfolder and delete this extra original file.
When I move these subfolders to my e readers, I'd like to have only one format.
E pub files for Nexus, and azw3 files for Kindle Fire.
I will appreciate if one of the gurus here show me how to make changes with calibre when I export these converted books.
Thank You kindly.
