Calibre convert script without source file

billmandy · 08-25-2021, 12:13 AM

Hello.
I am using the following script to convert all of the files in a specific folder to AZW. But the resulting files tend to be bog, like 30-40 MB or so, so I was thinking that maybe there is an option to not add the source file in in the final file.
KindleGen had a command like that for MOBI files.
Please help.

for /r %%1 in (*.mobi) do "PATH TO CALIBRE EXE" "%%~dpn1.mobi" "%%~dpn1.azw3"

Thank you for your reply.
I guess the book is big and that is it.

Could you tell me why there is this specific size difference betwen ebooks converted from the same file?
AZW3 is 40.7 MB
EPUB is 36.2 MB
MOBI is 40.7 MB

because epub uses a different type of compression than mobi/azw3
