File extension plb is related to Arena Simulation Software from Rockwell Automation. Arena is used to help demonstrate, predict, and measure system strategies for effective, efficient and optimized performance.
A .plb file contains picture library.
Use Arena Simulation Software to work with *.plb files.
If any program can somehow export *.plb files, it would be Arena Simulation Software.

Insight II was a graphical molecular modeling program developed by Accelrys Inc. A PLB file provides a library of pseudoatoms for use within the application.
Pseudoatom libraries are application data rather than standalone documents. Insight II uses the definitions in the library as part of its molecular modeling workflow.
Insight II was distributed for Linux and Unix systems and is now obsolete.
Open the file with Insight II on a compatible Linux or Unix system. Make the file available to the application as a pseudoatom library rather than opening it as a regular document.
Because the format is tied to Insight II, general text editors and modern molecular modeling programs may not interpret it correctly.
The PLB file is an Insight II pseudoatom library. Use the definitions in Insight II; moving them to another molecular modeling program may require recreating them in that program's library format.

MicroSim PCBoard was a PCB computer-aided design (CAD) application developed by Cadence Design Systems and associated with OrCAD PCB Designer. It provides tools for designing printed circuit boards.
A PLB file stores a package library for the application. The library provides package or footprint data that can be used when placing and designing components on a PCB.
This is a proprietary, application-specific library format rather than a general-purpose PCB interchange format. It is primarily relevant to legacy MicroSim PCBoard and compatible OrCAD PCB design workflows on Microsoft Windows.
Open the file with MicroSim PCBoard or a compatible version of OrCAD PCB Designer on Microsoft Windows. In most cases, the library is accessed from within the PCB design application's library or package-management tools rather than opened as a standalone document.
Compatibility can depend on the software version that created the library. Make a backup copy before attempting to load or modify a legacy library.
If a compatible version of MicroSim PCBoard or OrCAD PCB Designer can read the file, use its library-management or export functions to save the package data in a format supported by the target PCB design system.
If the file cannot be read by the available software, conversion may require recreating the package definitions in another PCB library format.

PhotoLine, developed by Computerinsel GmbH, is image-processing and image-editing software available for multiple desktop platforms, including Microsoft Windows and macOS. Its browser uses PLB files to maintain an index of images and display thumbnail previews.
A PLB file is a supporting file for the PhotoLine browser, not an image document intended for exchange between applications. It belongs to PhotoLine's internal browser data and is used together with the image files that it indexes.
Use PhotoLine on Windows or macOS to access PLB files. Normally, PhotoLine's browser reads the file automatically when it accesses the associated image collection.
Because the file contains browser index data and thumbnails rather than a standalone image, it may not display useful content when opened directly outside PhotoLine.
PLB files do not have a meaningful image-format conversion. They are PhotoLine browser indexes rather than image files.
To create converted images, open the original images in PhotoLine and export them to an appropriate image format.
