WTB is the extension for files used in Windows operating systems. WTB files work with the Win-Test program by Olivier F5MZN. Other programs also support WTB files. The data in WTB files saves in the Data Files format.
When you double-click a .wtb file, Windows checks the extension. If Windows does not recognize the .wtb extension, you get this message: “Select an app to open this file”. It means Windows does not have a default program for .wtb files.
To open .wtb files: Update the application you use to open them. Only the latest software version supports .wtb files. Check .wtb files for viruses with antivirus software. Associate Win-Test with .wtb files manually or through the Open With menu. The Windows Registry also associates file extensions with software.
WTB files work on Windows devices. The Data Files type covers 1326 file formats including .wtb. Win-Test software officially supports WTB files.
