Notes about the SQB file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The SQB file type is primarily associated with 'SQL Backup' by Red Gate Software Ltd.. SQL Backup is a tool for creating, compressing and protecting your SQL Server backups. This is a custom backup format. A converter is available with the program to convert the SQB file to a Microsoft Tape Format (MTF) file so it can be imported back into SQL Server.
