What is an OLB file?

Microsoft Windows Object Library

These OLB-files are object libraries. When a programmer compiles the source code of a Visual Basic program, the compiler will output an OLB file before everything is linked into an executable EXE file.

If you have lots of subroutines, you can compile them into an object library. Then you can link your primary source code against the object library to produce an .EXE file. This will save time as you do not need to re-compile everything.
