Thanks for your answers. I have made further investigation to my system. What I mean by "c:browser inaccessible" is that the item automatically generated by the installation of wine in the menu "wine" does not work. I have looked to what command this item is corresponding ? I have found "xdg-open ./win/dosdevices/c:" and the answer is something as "undefined mime-type". I understand that it imeans that some associations have not been set properly during the installation of wine. I do not know why ? However, that is not a big problem, because i have actualy access to c: by the usual file manager of KDE. Michel
