Opening OLB files

Did your computer fail to open an OLB file? We explain what OLB files are and recommend software that we know can open or convert your OLB files.

What is an OLB file?

The .olb file extension is most commonly used by Microsoft Office software applications. The OLB files contain object libraries. These libraries are referenced by the associated Microsoft application.

The .olb file extension is also used for VAX object library files, MTC data files, PSpice model files and AUTOGEN file.

Try a universal file viewer

In addition to the products listed above, I would suggest that you try a universal file viewer like Free File Viewer. It can open over 200 different types of files - and very likely yours too! Download Free File Viewer.
