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!!
I tested it with virustotal and virusscan.org. They both say there is a TROJAN VIRUS in it !!!
