Maybe I need a brief explanation of the options
The ePub manifest is a list of all files that are officially part of the book. This implies that it's supposed to be safe to remove any file that isn't in the manifest, because all files are supposed to get added to the manifest. However, some operating-specific files may get added without being added to the manifest. Notably, OS X stores a .DS_Store file just about everywhere, and some readers may drop bookmark or other status files without updating the manifest. It's not an error to have files not in the manifest, but it's not technically correct; usually this option doesn't change anything, not many books I've seen have files not in the manifest, but it may lead to smaller books and there were a few books I tried where the size difference was large relative to the size of the book.
Cleaning up ePub markup is, in my opinion, a good idea. What it will do, for every content file, is:
- Replace the Unicode versions of the en-dash and em-dash with three or two dashes, respectively.
- Remove empty header tags
- Remove Unicode replacement characters (they look like �)
- Remove cruft from any Microsoft applications that may have been involved in creating the ePub content
Depending on your source book, this may not change much (or anything) but this option I would recommend people use.
Blocking the Analytics DB is really up to your own personal preference and what you're comfortable with. I think, and maybe I'm wrong, that this DB table stores events for sending to Google Analytics when the Kobo device is connected to the Internet. See
https://www.mobileread.com/forums/sho...d.php?t=162713 for an outline, but the thread is old now and may be outdated. If I'm right about the purpose of this DB table, blocking entries from going to it will prevent any analytics data from going to Kobo through Google Analytics since the device will always think there's no analytics to report!
