Since your Emacs is a 64-bit build, a 1GB file shouldn't be too big,
provided that your system has enough virtual memory to support reading
it into memory (which might require more than 1GB, perhaps up to 2GB).
If Emacs says "Memory exhausted" when you visit that file, try
enlarging the size of swap for your system.
