Record marked as obsolete and not updated for a long time.
The ng file extension is associated with Norton Guide, a hypertext documentation system developed by Peter Norton Computing in 1985.
An ng file stores an online documentation database, including the documentation content and its hypertext links for browsing in Norton Guide.
Norton Guide was designed for DOS-based systems and is now obsolete. Existing files may still be readable with compatible viewer software.
Open an ng file with Norton Guide or a compatible viewer. ViewAng is an application that can open Norton Guide databases and is available from the White Town online database.
Because Norton Guide is obsolete, a compatible viewer may be required on current operating systems.
Open the database with Norton Guide-compatible software and manually copy or extract the documentation into a current document format if conversion is necessary.
