The olb file extension is used by Synergy/DE, an integrated development environment from Synergex for creating applications with the Synergy DBL programming language.
An olb file stores compiled Synergy DBL object modules in a library. Synergy/DE development and build tools use the library when linking applications, so it forms part of a Synergy/DE project's compiled output.
The format is specific to Synergy/DE and is supported on Microsoft Windows through the Synergy/DE software. It is not a general-purpose object or archive format.
Open or use the olb file with the Synergy/DE development and build tools on Microsoft Windows. It normally belongs to a Synergy/DE project or application rather than being opened directly.
A text editor or general archive utility cannot display the compiled object modules in a useful form.
There is no general-purpose converter for the Synergy/DE olb file format. If the library must be recreated, rebuild it from the original Synergy DBL source files with the appropriate Synergy/DE tools.
