I guess everyone has seen the following warning (at some point or another) when trying to open a relatively large file in Emacs:
By default Emacs will display this warning for every file bigger than 10MB, which is quite annoying (conservative), especially given the fact that on any modern computer even much bigger files will be loaded almost instantaneously and won’t slow down Emacs significantly.
You can adjust this behavior by altering the value of the
large-file-warning-threshold variable. I’d suggest setting it to
something like 100MB:
Alternative, you can set it to
nil, which will suppress the
warning permanently, regardless of the size of the file you’re trying to open.
P.S. By the way, it’s not particularly wise to edit huge files (say bigger than 1GB) in Emacs directly. If you need to do something like this I’d suggest taking a look at the excellent vlfi package.
