Bianca,

As mentioned before, the data only gets written at the end of a MediaLab session, so there isn't any way to save responses until all of the files in the .exp file for a session are run.

Take a look at this section of the MediaLab manual describing the use of autostart files:

If you put each .exp file in its own folder, you could try putting the same autostart file in the folder with it. This might allow you to avoid entering subject IDs, but you would still need to start a new session for each of the .exp files in their own folder.
