At least I have that much correct so far.

Whether you do or not depends on whether the existance has a potential for
change during the course of running any incarnation of the program.  If it
-can- disappear, you may as well skip the (tiny) overhead of using a dummy
variable, as you need to check it every time.  If it can't, then you may as
well use a dummy once and only perform the exists() check on the file if
the situation warrants it.

Well, I deleted your original code earlier.  If you repost, I'll take a
peek at it again.  I can't tell from memory what you may have gotten wrong
in your code.  My pseudocode should have been a fair example of how to go
about it though.

By by all means, repost the relevant code and we'll have a look.
