Hi Shawn,

You can setting a flag in an ApplicationState, e.g.
Application["fileAccessed"]. In Application_Start set it as false,

Application["fileAccessed"] = false;

Only when it's false to allow to access and shift it to true and also set a
flag in Session. Once finish accessing the file to shift Application flag to
false and delete Session flag. Or in Session_End to check Session flag,
accordingly shift Application flag.
