Open TN3 File

The TN3 extension files are animated bitmap images used by Atari ST systems, developed in the late 1980s and early 1990s.

These files store multiple frames of bitmaps and the speed and duration of the animation sequence. They are basically used to reproduce high resolution animated graphics.

As mentioned above, the graphics contained in a TN3 file are high resolution, and the terminal number of the extension (3) indicates that they are indeed high resolution, this means that small images are also stored in a similar format of low resolution, in this case TN1 files, and consequently, medium resolution, TN2 files.

To open files with the TN3 extension you must have the program installed:
