This extension exposes low-level C file functions (stdio.h) to you under file_raw_ prefix.
These allow for buffer-styled operations on files, as well as a few extras (e.g. flushing changes to a file without costly close-reopen, or reading X characters from a file as a string).
Also, in the name of performance and not spending too much time on a free extension, it does not do too much error checking, so you might be able to crash your game if you try hard enough.
