Recommend!! Well done, Andrea Vacondio! Very useful, worked right on the first time: the manual is very simple. Bad reviews about lacking the manual are, to be polite, unfair because: a) it's a, guess what, pdfsam tutorial.pdf file that comes with the instalation package, accessible from the start menu>all progrmams>PDF split and merge, b) it's easily found at pdfsam.org, and c) there are also forums, FAQ sections, even tips at pdfsam.org!!
One of those programs that will give you no clue on how to use it without reading a manual. Non-intuitive. No manual provided.
