I'd like to launch some opendialog objects with a default location,
to avoid to navigate among different directories as I know the exact
path to search in. With 'path' -> [thispatcher] I easily get the
parent directory of subdirectories I'm interested in (like "Audio",
"Colors","Presets" or "Scores"). But I don't know how to use these
paths with the opendialog objects I use. Do someone know?
