Zipeg
Zipeg is* an open source free software that extracts files from a wide range of compressed archive formats. Zipeg works under Mac OS X and Windows. It is best known for its file preview ability. It is incapable of compressing files, although it is able to extract compressed ones. Zipeg is built on top of the 7-Zip backend. Its UI is implemented in Java and is open source. The list of supported archive formats includes: ZIP, 7z, RAR, ARJ, LHA/LZH, TAR, GZ, TGZ, CPIO, BZIP2, RPM, CHM, Z, ISO, CBR, CBZ, EAR and WAR. Zipeg automatically detects filenames in national alphabets (code pages) and correctly translates them to Unicode. Zipeg reads Exif thumbnails from JPEG digital photographs and uses them for "tool tip" style preview and item icons. The development has halted since version 2.9.4 from July 2012, the website zipeg.com is no longer available and the source code has also been archived. (Though that happened automatically when Google Code was archived in early 201 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gzip
gzip is a file format and a software application used for file compression and decompression. The program was created by Jean-loup Gailly and Mark Adler as a free software replacement for the compress program used in early Unix systems, and intended for use by GNU (from where the "g" of gzip is derived). Version 0.1 was first publicly released on 31 October 1992, and version 1.0 followed in February 1993. The decompression of the ''gzip'' format can be implemented as a streaming algorithm, an important feature for Web protocols, data interchange and ETL (in standard pipes) applications. File format gzip is based on the DEFLATE algorithm, which is a combination of LZ77 and Huffman coding. DEFLATE was intended as a replacement for LZW and other patent-encumbered data compression algorithms which, at the time, limited the usability of compress and other popular archivers. "gzip" is often also used to refer to the gzip file format, which is: * a 10-byte header, contai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Data Compression
In information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original representation. Any particular compression is either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lossless compression. Lossy compression reduces bits by removing unnecessary or less important information. Typically, a device that performs data compression is referred to as an encoder, and one that performs the reversal of the process (decompression) as a decoder. The process of reducing the size of a data file is often referred to as data compression. In the context of data transmission, it is called source coding; encoding done at the source of the data before it is stored or transmitted. Source coding should not be confused with channel coding, for error detection and correction or line coding, the means for mapping data onto a signal. ...

Zip (file Format)
ZIP is an archive file format that supports lossless data compression. A ZIP file may contain one or more files or directories that may have been compressed. The ZIP file format permits a number of compression algorithms, though DEFLATE is the most common. This format was originally created in 1989 and was first implemented in PKWARE, Inc.'s PKZIP utility, as a replacement for the previous ARC compression format by Thom Henderson. The ZIP format was then quickly supported by many software utilities other than PKZIP. Microsoft has included built-in ZIP support (under the name "compressed folders") in versions of Microsoft Windows since 1998 via the "Windows Plus!" addon for Windows 98. Native support was added as of the year 2000 in Windows ME. Apple has included built-in ZIP support in Mac OS X 10.3 (via BOMArchiveHelper, now Archive Utility) and later. Most free operating systems have built in support for ZIP in similar manners to Windows and Mac OS X. ZIP files ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Softonic
Softonic.com is a web portal based in Barcelona, Catalonia, Spain. It was founded in June 1997 and is owned by Softonic International. History Softonic started in 1996 as a file-oriented download service called Shareware Intercom, at Intercom Online (Grupo Intercom), a provider of Internet services in Cerdanyola del Vallès, near Barcelona (Catalonia, Spain). Files for the website originally came from the "Files Library Intercom BBS" at Intercom Online, using a "5-step semi-automated process", which was later greatly simplified. The company also offered monthly CDs of its software library for users tired of "having to wait for downloads to complete or pay exorbitant phone bills." In 1999, the service was described as having a "generosity of games, antivirus, education and the long, seductive etcetera." In 2000, the company became independent under the name Softonic. In 2004, Softonic was made available in German, and in 2005, English. Initially the service was oriented only to d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EAR (file Format)
EAR (''E''nterprise ''A''pplication a''R''chive) is a file format used by Jakarta EE for packaging one or more modules into a single archive so that the deployment of the various modules onto an application server happens simultaneously and coherently. It also contains XML files called deployment descriptors which describe how to deploy the modules. Ant, Maven, or Gradle can be used to build EAR files. File structure An EAR file is a standard JAR file (and therefore a Zip file) with an .ear extension, with one or more entries representing the modules of the application, and a metadata directory called META-INF which contains one or more deployment descriptors. Module Developers can embed various artifacts within an EAR file for deployment by application servers: * A Web module has a .war extension. It is a deployable unit that consists of one or more web components, other resources, and a web application deployment descriptor. The web module is contained in a hierarchy of ...

Comic Book Archive
A comic book archive or comic book reader file (also called sequential image file) is a type of archive file for the purpose of sequential viewing of images, commonly for comic books. The idea was made popular by the CDisplay sequential image viewer; since then, many viewers for different platforms have been created. Design Comic book archive is not a distinct file format. It is a filename extension naming convention. The filename extension indicates the archive type used: * .cb7 → 7z * .cba → ACE * .cbr → RAR * .cbt → TAR * .cbz → ZIP Comic book archive files mainly consist of a series of image files with specific naming, typically PNG (lossless compression) or JPEG (lossy compression, not JPEG-LS or JPEG XT) files, stored as a single archive file. Occasionally GIF, BMP, and TIFF files are seen. Folders may be used to group images in a more logical layout within the archive, like book chapters. Comic book archive viewers typically offer various dedicated f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microsoft Compiled HTML Help
Microsoft Compiled HTML Help is a Microsoft proprietary online help format, consisting of a collection of HTML pages, an index and other navigation tools. The files are compressed and deployed in a binary format with the extension .CHM, for Compiled HTML. The format is often used for software documentation. It was introduced as the successor to Microsoft WinHelp with the release of Windows 95 OSR 2.5 and consequently, Windows 98. Within the Windows NT family, the CHM file support is introduced in Windows NT 4.0 and is still supported in Windows 11. Although the format was designed by Microsoft, it has been successfully reverse-engineered and is now supported in many document viewer applications. History Microsoft has announced that they do not intend to add any new features to HTML Help. File format Help is delivered as a binary file with the .chm extension. It contains a set of HTML files, a hyperlinked table of contents, and an index file. The file format has been reverse- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RPM Package Manager
RPM Package Manager (RPM) (originally Red Hat Package Manager, now a recursive acronym) is a free and open-source package management system. The name RPM refers to the file format and the package manager program itself. RPM was intended primarily for Linux distributions; the file format is the baseline package format of the Linux Standard Base. Although it was created for use in Red Hat Linux, RPM is now used in many Linux distributions such as PCLinuxOS, Fedora, AlmaLinux, CentOS, openSUSE, OpenMandriva and Oracle Linux. It has also been ported to some other operating systems, such as Novell NetWare (as of version 6.5 SP3), IBM's AIX (as of version 4), IBM i, and ArcaOS. An RPM package can contain an arbitrary set of files. Most RPM files are “binary RPMs” (or BRPMs) containing the compiled version of some software. There are also “source RPMs” (or SRPMs) containing the source code used to build a binary package. These have an appropriate tag in the file header tha ...

CPIO
cpio is a general file archiver utility and its associated file format. It is primarily installed on Unix-like computer operating systems. The software utility was originally intended as a tape archiving program as part of the Programmer's Workbench (PWB/UNIX), and has been a component of virtually every Unix operating system released thereafter. Its name is derived from the phrase ''copy in and out'', in close description of the program's use of standard input and standard output in its operation. All variants of Unix also support other backup and archiving programs, such as tar, which has become more widely recognized. The use of cpio by the RPM Package Manager, in the initramfs program of Linux kernel 2.6, and in Apple's Installer (pax) make cpio an important archiving tool. Since its original design, cpio and its archive file format have undergone several, sometimes incompatible, revisions. Most notable is the change, now an operational option, from the use of a binary forma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
