An Entity of Type: Format106636806, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The .LBR file format was an archive file format invented by Gary P. Novosielski used on CP/M and DOS operating systems during the early 1980s. Packages in .LBR format were created by the LU program. It can act in interactive and parameter-driven mode, and can add, extract, delete files from the LBR package. A companion program, still developed by Novosielski, is LRUN.COM : a small program which allows running a .COM (executable code) directly from any library, without having to extract it to a separate disk file.

Property Value
dbo:abstract
  • LBR ist ein Dateiformat zur Datenarchivierung. Bekanntheit erlangte das Format unter dem Betriebssystem CP/M und dem darin enthaltenen Kommandozeilenprogramm LU (später NULU). Es wurde meist in Kombination mit den Komprimierern/Entpackern CR/UNCR („[un-]crunch“) oder SQ („squeeze“) verwendet, die Dateien erhielten dann jeweils die Dateiendung .LZR respektive .LQR je nach dem Algorithmus.Es war auch noch unter DOS in Verwendung, wurde dann aber durch bessere Formate wie ARC und später PAK, LZH, ZIP und RAR ersetzt. Heute werden noch Emulatoren für [NU]LU angeboten, um solche Dateien zu lesen. Die Dateiendung .LBR („Library“ für ‚Bibliothek‘) ist nicht eindeutig. Mehrere jeweils zueinander nicht kompatible Formate wurden im Lauf der IT-Historie entwickelt, so zum Beispiel von IBM zur Auslieferung von Software in den 1980er Jahren. (de)
  • The .LBR file format was an archive file format invented by Gary P. Novosielski used on CP/M and DOS operating systems during the early 1980s. Packages in .LBR format were created by the LU program. It can act in interactive and parameter-driven mode, and can add, extract, delete files from the LBR package. A companion program, still developed by Novosielski, is LRUN.COM : a small program which allows running a .COM (executable code) directly from any library, without having to extract it to a separate disk file. Later compatible programs like NULU arrived for .LBR creation, and many tools such as LT and QL were capable of extracting from .LBR archives. .LBR is an abbreviation of "Library", and, resembling the .tar file format, member files were only stored in the .LBR file, not compressed. As transfer of LBR files by modem was common, it was typical practice for archiving a collection of files to compress them using the SQ or programs then store them in an .LBR archive, or else (more rarely) store the files in the LBR archive, then use SQ or CRUNCH to compress the archive. A compressed LBR archive file was given the extension ".LQR" (if squeezed) or ".LZR" (if crunched); however, it was more common to compress the members of the archive than to compress the archive as a whole. As MS-DOS and other operating systems became more popular and displaced CP/M, .LBR's popularity waned. The development of the ARC archiver which both compressed and archived files in one program went a long way towards displacing .LBR on MS-DOS systems; on CP/M systems, .LBR persisted longer due to the lack of a useful ARC port.
