The TYSET file extension is associated with Typinator, a text expansion utility from Ergonis for Apple macOS. Typinator automatically replaces defined abbreviations with longer text blocks, such as frequently used phrases or words.
A .tyset file contains a Typinator set and its text expansion entries. The set forms part of Typinator's collection of user-defined abbreviations and expansions.
The format is intended for use with Typinator on macOS rather than as a general-purpose text document. It remains associated with the macOS version of Typinator.
Open a .tyset file with Typinator on macOS. Typinator can load the set and make its abbreviations and text expansions available in the application.
A .tyset file is not normally converted to another document format because it contains Typinator expansion data rather than ordinary document text. Use Typinator's set management or export features, where available, to move the entries to another Typinator set.
Converting the file to plain text preserves only readable text and does not preserve the abbreviations and expansion settings.
