Quote - So you're telling us that a program that only reads text files is safe? How do you get this funny idea?

I suppose that you know what is a text file or am I wrong?
3ds format is not a text file, but is also 100% secure.
Any file, text or binary that has no executable code is 100% secure.

A simple text file with a Window function call:

MessageBox(0,"hello","make me run",0);

Try to do Windows make appear the message "make me run" using this text file with anything you want.

It's clear or too complicated yet?

Stupidity also evolves!
