The Delphi VCL TFileOpenDialog has a property called ClientGUID. Embarcadero documentation says it:
...holds a GUID associated with a dialog's persisted state. Persisted states for a dialog can include such things as its position and size...
But that is all it says. I would like to know more. My testing shows that the dialog Size and Position do persist between application sessions so they are being stored somewhere.
But where is this information being stored? (I have searched the registry and hard drives for the GUIDs I have been testing but cannot find them anywhere.)
And, is it only Size and Position or do other properties also persist? (If it is only Size and Position then it's not really very useful to me.)
