three @Alex V. At this time, I don't know what I was speaking about. I believe this will happen to be a reference to lock-no cost programming, but it's not really accurate to claim that depends on race problems, per se.
Your system can not promise that A different process on the pc has not modified the file. It can be what Eric Lippert refers to being an exogenous exception. You cannot stay away from it by examining with the file's existence beforehand.
