&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;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.&lt;br /&gt;
&lt;br /&gt;
''New in PyMOL 1.8''&lt;br /&gt;
&lt;br /&gt;
== Examples ==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;syntaxhighlight lang=&amp;quot;python&amp;quot;&amp;gt;&lt;br /&gt;
fetch 1ubq&lt;br /&gt;
&lt;br /&gt;
set pse_binary_dump, off&lt;br /&gt;
save regular.pse&lt;br /&gt;
&lt;br /&gt;
set pse_binary_dump, on&lt;br /&gt;
save binary.pse&lt;br /&gt;
&lt;br /&gt;
# compare file size&lt;br /&gt;
print(os.path.getsize(&amp;quot;regular.pse&amp;quot;))   # prints 215482&lt;br /&gt;
print(os.path.getsize(&amp;quot;binary.pse&amp;quot;))    # prints 118557&lt;br /&gt;
&amp;lt;/syntaxhighlight&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Known Limitations ==&lt;br /&gt;
&lt;br /&gt;
* Before 2.4: [https://pymol.org/dokuwiki/doku.php?id=properties#atom_level_properties Atom Properties] not supported&lt;br /&gt;
&lt;br /&gt;
== See Also ==&lt;br /&gt;

* [[pse_export_version]]&lt;br /&gt;
