The PLB (Premiere Library) extension indicates a file used by Adobe Premiere, an application part of the Adobe Creative Suite developed by Adobe Systems Inc. and designed for video editing, graphic design and web development. Adobe Premiere is a timeline-based application and constitutes the video editing component of the suite. The first version was released in 1991 with over 10 iterations following until version 7 when Adobe rewrote the source code of the entire program and changed its name to Adobe Premiere Pro.

PLB files are Windows only library files created with Adobe Premiere 6.X. They can contain several clips from a single project or from multiple projects. Adobe Premiere Pro doesn’t support PLB files directly but allows Windows users to import library files into existing projects. When imported, a library is immediately converted into a bin.

How to open PLB files

Windows users can open PLB files with Adobe Premiere or import them into Adobe Premiere Pro. PLB files are not supported on the Mac OS or Linux platforms. To use the contents of a PLB file on a Mac, users have to first save it to a Mac-compatible format with Adobe Premiere Pro.
