Notes about the MS9 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 MS9 file type is primarily associated with 'Multisim' by National Instruments Corporation. The NI Electronics Workbench Group (formerly Electronics Workbench) equips the PCB designer with tools for schematic capture, interactive circuit simulation with SPICE, board layout with autorouting options, and integrated prototyping and test.
