The LQR file type is mainly related to a compressed archive file that covers one or more files that have been abridged in terms of file size for easy distribution via the Internet or through transferrable media like optical disks such as DVDs and CDs among other exterior data storage devices. Any file stored in LQR File format can be combined with compression provisions executed by a certain compression algorithm. Files in the LQR format are pinned with the .lqr extension. Now, the LQR extension has been substituted by more extensively used compression standards and encoding features, including the RAR and ZIP format.
In the early 1980s, the LBR file format was an archive file format used on CP/M and MS-DOS operating systems LBR files characteristically confined files handled by SQ, or the archive itself was compressed with SQ. A compressed LBR archive file was given the extension LQR or LZR.
