Is it possible to avoid the "File X is too large, really open?" confirmation?
If not, would it be possible for Emacs to remember my answer the first time I visited a large file? If I visited it once, I will surely want to really visit it again.
The variable is
large-file-warning-threshold is a variable defined in `files.el'. Its value is 10000000 Documentation: Maximum size of file above which a confirmation is requested. When nil, never request confirmation. You can customize this variable. This variable was introduced, or its default value was changed, in version 22.1 of Emacs.
I found this by using
helm-apropos and searching for "large file".
