myBase is an information management system developed by Wjj Software. Its native database format uses the .nyf file extension.
An .nyf file contains a myBase database, including the information organized within the application. The file is used as the database for a myBase workspace rather than as a standalone document.
myBase is available for Microsoft Windows, Linux and macOS systems. This record links the format with myBase Desktop for Microsoft Windows.
Open the file with myBase Desktop on Microsoft Windows. In myBase, use the application's Open command and select the .nyf file.
Compatible myBase editions for Linux or macOS can also be used if the file is being opened on one of those systems.
Open the .nyf file in myBase and use the application's built-in export features when the database contents need to be moved to another format.
