</ref> although sometimes different extensions are used to indicate general content, e.g. <code>.ocx</code> for a [[Object Linking and Embedding|OLE]] library.

A <code>.lib</code> file can be either a static library or contain the information needed to build an application that consumes the associated DLL. In the latter case, the associated DLL file must be present at runtime.
