The pse_binary_dump setting affects the PyMOL session file format (.pse). If set to on, session export will be significantly faster and produce smaller files.

New in PyMOL 1.8


fetch 1ubq

set pse_binary_dump, off
save regular.pse

set pse_binary_dump, on
save binary.pse

# compare file size
print(os.path.getsize("regular.pse"))   # prints 215482
print(os.path.getsize("binary.pse"))    # prints 118557
