File extension SIB (.SIB) information

If Windows is unable to open SIB files you may not have the appropriate program installed or may have a registry related error. We strongly recommend that you run a free registry scan.

Appropriate program:

The .SIB file extension identifies music score files created using Sibelius Score software. Sibelius Score allows the user to write music using normal musical notation and then playback the written score electronically.. Incorrect associations are the cause of many file extension errors. Scan your system to prevent and identify association errors.
