Notes about the NTV 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 NTV file type is primarily associated with 'PatternSmith' by Autometrix. Autometrix makes automatic cutting machines and software to run them. This is an import file; to use the file it has to be converted to .PAT format by the software.
