Re: Can I mix the use of fold-expr with fold-marker just as mixing fold-expr with fold-manual?

Where that file is stored should be documented in :help :mkview or one of the linked help topics. I suggested you create a fold expression to use with foldmethod=expr. This expression is best placed into a function which is loaded with the rest of your Vim config. Alternatively, you can create a one-liner expression (not a function) and put it in a modeline in the file itself, but that is generally less useful.

Thanks Ben, I will conform to the convention and won't top-post in future.
By 'storing' I actually did not refer to persisting, but temporary. When I use foldmethod=expr to automatically fold up my classes, the foldlevel must be 'stored' somewhere, or otherwise after I switch to manual it would have been all lost. Is there something I'm wrong about this model? Then where does Vim temporarily store such thing? Enviroment variables? Or something?
