How to configure Telelogic Synergy so that the default type for "unknown" file is binary rather than ascii ?

Question

Hi,

if I am not wrong, Telelogic Synergy mapped new files to a type depending of their extensions.

If the extension is unknown, the file is by default declare as a base type ascii.

Is it possible to make sure that "unknown" file type end up as binary rather than ascii ?

Thanks,

Thomas
