Notes about the SS4 file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The SS4 file type is primarily associated with 'SigScribe4' by MODRATEC. SigScribe4 is your personal signal engineering department. It gives you the capability to design interlocking lever frames to operate the signals and points on your model railway.
