Record marked as obsolete and not updated for a long time.

Racter was an artificial-intelligence simulator from 1984. Similar to ELIZA, it converses with the user until boredom occurs.

A .rac file contains data used by Racter during its conversations. It is an application-specific file that works as part of the Racter program rather than as a standalone text or document file.

Racter was made for Microsoft MS-DOS. The format is obsolete and is no longer used by current software.

How to open rac file?

Open the file with the original Racter program in a compatible Microsoft MS-DOS environment. On a modern computer, an MS-DOS emulator may be required.

Opening the file in a text editor is unlikely to provide a useful representation because it is intended for use by Racter.

How to convert rac file?

Racter data is intended for use by the Racter program rather than conversion to a common document format.

To preserve readable conversation output, run Racter and copy or transcribe the displayed text separately.
