Notes about the WST 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 WST file type is primarily associated with 'GridImp' by Winwaed Software Technology LLC. GridImp is designed to plot contour-like datasets that are indexed by coordinates, rather than by place names for use in Microsoft MapPoint. This file is an XML-based format used by GridImp to store custom color palettes for use in MapPoint. The file format was intended to hold other MapPoint-related information, but this has yet to be realized.
