The LZR file type is primarily associated with 'Compressed Archive File'. The .LBR file format was an archive file format used on CP/M and MS-DOS operating systems during the early 1980s. LBR archives typically contained files processed by SQ, or the archive itself was compressed with SQ. A compressed LBR archive file was given the extension .LQR (if squeezed) or .LZR (if crunched).
