when i install a window program using the installer i can open the a file without problems using the file manager because the program had created a *.desktop file to link the program with the file exention. The *.desktop uses /ProgIDOpen. I know that these IDs are defined in regedit in
but there must be more. This only defines an ID, so that *.ext is linked with a specific ID. How does wien know what program should used to open the file know. Is there an extra link between the ID and the program itself?
