What is a LIBPKG file? A LIBPKG file is an integrated library project created by Altium Designer, a CAD application used by engineers to design printed circuit boards (PCBs). It contains a set of PCB design documents that make up an integrated library, which includes schematic libraries and paths to the model libraries.

More Information The LIBPKG file type is a native project format only associated with Altium Designer. To create a LIBPKG file, select File → New → Project → Integrated Library then select File → Save Project As . Altium Designer users typically compile LIBPKG files to integrated libraries (INTLIB files) in order to store all the component information for a design in one portable and secure file. To compile a LIBPKG file to an INTLIB file, select Project → Compile Integrated Library or right-click the LIBPKG file and select Compile Integrated Library .
