You don't need ten GB of ram to open that, with a text-editor built for being able to handle such large files. The solution is pretty easy: read the file into memory only in chunks.

Database dump, Log-Files, text-file with losts binary data attached (I know lots of *nix-installers doing this). There are endless use-cases.

So? Nobody said he's going to print this.
