Probably. In fact, if this is a problem, then it is likely to always be a
problem.

Yes. When I said it is common, I was mainly refering to the technique of
calling a function twice; once to get the sizw required for the data, then
again for the data.

Where is it suggested that that be done?

That is a guess, correct? We don't know what the dialog would do if we
select so many files that the size required would be too big. It is possible
that the dialog would not allow it.
