Tails and its Book Maker

I down loaded, torrent files of Tails and FreeNAS.
Unfortunately my DATA finished and larger of FreeNAS fell short of few MBs.
Thanks FreeNAS for your torrent file.
I do not like direct download.
For Tails I used image writer writer to boot.
It booted well but failed integrity its software.
From the booted OS I made another bootable USB.
Its image is only 1GB but expanded to 4.3GB.
It has a bookmaker utility and makes A 3 to A 5 books.
I tried a book file made of AbiWORD for conversion to book but it failed, saying EOF or end of the file error.
I will do a bit of editing to my big file and see I can make A 5 Book.
I hope Tails improve bookmaker identify ABI and LibreOffice long file.
I hope Tails add custom utility to get real book sizes printed out.
