Hi Melissa,

Molecular surfaces make session files very large because they save all the surface triangles.  Did you have a molecular surface in that large session?  I have considered not saving the molecular surfaces and just recomputing them although that will make restoring the session slower as it tries to recompute the surface.

What deterimines the file size of saved ChimeraX sessions (.csx files)?  I saved a session of one structure (6Y5q) at 4 MB, and another structure  (6y50) at 2.6 MB.  However, when I saved a session with both structures open, it was a whopping 120.6 MB.  Is there a way to reduce that file size?
