p4patch
Generate patch via "p4" command line for Perforce. "p4 diff" ignores newly added files, this utility includes new files in the patch.
Ensure that 'p4' can run successfully in the terminal, then go to the working p4v local folder, just run:
p4patch
or
p4patch > patch.txt
You can cherry pick the containing folders by running p4patch in different folders and then concatenate the output in a single patch file. For example:
cd /project1
p4patch > /documents/mypatch.txt
cd /project2
p4patch >> /documents/mypatch.txt
cd /project3
p4patch >> /documents/mypatch.txt
