I can't really answer the question; I reject its underlying assumption
that I *would* use a file stream to move a file. Using the API, you have
a much better chance of retaining NTFS security, encryption,
compression, and stream information. TFileStream is ignorant to all that.

I'd accept the question if it were rephrased: "Under what circumstances
might someone prefer to use a file stream to move a file rather than
some other technique?"

One reason might be that the API function (or whatever other technique)
is not available or reliable on all the program's target systems.

Or maybe the API function is too complicated, making it easier to
re-implement the functionality from scratch than to spend time
understanding how to use the existing function.
