LBR (file Format)
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.LU v210 User Manual from SimTel archiv 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 In computing, tar is a computer software utility for collecting many files into one archive file, often referred to as a tarball, for distribution or backup purposes. The name is derived from "tape archive", as it was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archive Formats
In computing, an archive file is a computer file that is composed of one or more files along with metadata. Archive files are used to collect multiple data files together into a single file for easier portability and storage, or simply to compress files to use less storage space. Archive files often store directory structures, error detection and correction information, arbitrary comments, and sometimes use built-in encryption. Applications Portability Archive files are particularly useful in that they store file system data and metadata within the contents of a particular file, and thus can be stored on systems or sent over channels that do not support the file system in question, only file contents – examples include sending a directory structure over email, files with names unsupported on the target file system due to length or characters, and retaining files' date and time information. Additionally, it facilitates transferring high numbers of small files such as resource ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CP/M
CP/M, originally standing for Control Program/Monitor and later Control Program for Microcomputers, is a mass-market operating system created in 1974 for Intel 8080/ 85-based microcomputers by Gary Kildall of Digital Research, Inc. Initially confined to single-tasking on 8-bit processors and no more than 64 kilobytes of memory, later versions of CP/M added multi-user variations and were migrated to 16-bit processors. The combination of CP/M and S-100 bus computers became an early standard in the microcomputer industry. This computer platform was widely used in business through the late 1970s and into the mid-1980s. CP/M increased the market size for both hardware and software by greatly reducing the amount of programming required to install an application on a new manufacturer's computer. An important driver of software innovation was the advent of (comparatively) low-cost microcomputers running CP/M, as independent programmers and hackers bought them and shared their crea ...

SQ (program)
SQ (''squeeze'') is a computer program, devised by Richard (Dick) Greenlaw circa 1981, which was used in the early 1980s on both DOS and CP/M computer systems to compress files so they use less space. Files compressed by SQ are identified by changing the middle initial of the extension to "Q", so that text files ended with the extension , executable files ended with the extension or , documents with , etc. SQ used static Huffman coding as the compression algorithm. Groups of files were often combined into an archive using the LU program, which created .LBR files containing all the files needed for a particular group, such as all the files needed to install an application. Typically such files were either individually compressed (because LU did not compress files) or the LBR archive was itself compressed with SQ (similarly to the use of tar and gzip together). With the development of the ARC program (which combined both compression and archiving into one program) and its ARC ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
