Might be worth starting with something simple: ask for one directory
(the default or most obvious place), or ask for a full list of
plausible directories to try. Then a config manager could be built on
top of that which would handle write location selection, migration,
etc, and that would be a separate proposal that makes use of the
appdata module for the cross-platform stuff.
