Sorry, that's bad advice, a program should always assume filing system 
data may be altered by other processes.

1) Obviously if its a Wimp application, other tasks are running
2) If the single tasking program can be run a in taskwindow or graphic
    taskwindow, other tasks are running
3) If the file is on a remote filing system, other machines may alter it
4) If the file is on a local filing system which is shared, other
    machines may alter it.

So only if you are outside the desktop, and storage is on a local non 
shared disc, can you be sure it wont be altered by anything else.

Only if its running outside the desktop. Inside the desktop the mode can 
change, so you need to ensure you handle the mode change message an 
re-read any mode related parameters you are using.
