Gesture settings can be saved to and loaded from a file via the Menu Bar item entry. This allows for gesture configuration sets to be loaded as required for specific desktop / application use or to save/share configurations.
When saving a profile (.gpf) can be placed in the UPDD folder but they can also put it in the equivalent folder in the user-level library directory, i.e.: ~/Library/Application Support/UPDD.
This is because it's standard in OS X for it to be allowable to use both folders, especially since the user-level folder doesn't require administrator access to modify.
