Split PDF Dialog

The Split PDF functionality allows you to split or 'explode' a PDF into smaller PDFs. You can split per page or per set number of pages. To split the PDF once, at a particular page refer to the Split PDF at current page function.

This dialog is invoked from the file menu option, 'Split PDF into many PDFs...'.

Filename pattern

This can contain control codes to name the file based on date, time, automatic incrementing numbers and environment varaibles.
The default pattern is '%Y-%m-%d {AUTONUM3}.pdf' which produces files named such as '2018-10-22 001.pdf','2018-10-22 002.pdf' etc.

For details on this, please read

Pages per PDF
