TN1 to DGN Conversion: FAQ

What are TN1 files?

TN1 is an archaic format associated with Atari ST — a brand of personal computers that used to be popular in the 1980s and 1990s. TN1s represent compressed bitmap images created or edited using image software designed for Atari computers, such as Tiny Stuff or Tiny View. Opening such files with currently available image viewers is probably difficult, so conversion might be the best option.

DGN stands for "design" and represents an extension typically used for CAD (Computer Aided Design) files created with Bentley Systems' MicroStation or with IGDS (Intergraph's Interactive Graphics Design System) — two popular programs used by architects, engineers, constructors and designers.
