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halted since version 2.9.4 from July 2012, the website zipeg.com is no longer available and the source code has also been archived.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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BZIP2
bzip2 is a free and open-source file compression program that uses the Burrows–Wheeler algorithm. It only compresses single files and is not a file archiver. It relies on separate external utilities such as tar for tasks such as handling multiple files, and other tools for encryption, and archive splitting. bzip2 was initially released in 1996 by Julian Seward. It compresses most files more effectively than older LZW and Deflate compression algorithms but is slower. bzip2 is particularly efficient for text data, and decompression is relatively fast. The algorithm uses several layers of compression techniques, such as run-length encoding (RLE), Burrows–Wheeler transform (BWT), move-to-front transform (MTF), and Huffman coding. bzip2 compresses data in blocks between 100 and 900 kB and uses the Burrows–Wheeler transform to convert frequently recurring character sequences into strings of identical letters. The move-to-front transform and Huffman coding are then ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Windows Compression Software
Windows is a product line of proprietary graphical operating systems developed and marketed by Microsoft. It is grouped into families and subfamilies that cater to particular sectors of the computing industry – Windows (unqualified) for a consumer or corporate workstation, Windows Server for a server and Windows IoT for an embedded system. Windows is sold as either a consumer retail product or licensed to third-party hardware manufacturers who sell products bundled with Windows. The first version of Windows, Windows 1.0, was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). The name "Windows" is a reference to the windowing system in GUIs. The 1990 release of Windows 3.0 catapulted its market success and led to various other product families, including the now-defunct Windows 9x, Windows Mobile, Windows Phone, and Windows CE/Embedded Compact. Windows is the most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macworld
''Macworld'' is a digital magazine and website dedicated to products and software of Apple Inc., published by Foundry, a subsidiary of IDG. History ''Macworld'' was founded by David Bunnell and Cheryl Woodard (publishers) and Andrew Fluegelman (editor). It began as a print magazine in 1984, with its first issue distributed at the launch of the Macintosh computer. As a print magazine, it had the largest audited circulation (both total and newsstand) of Macintosh-focused magazines in North America, more than double its nearest competitor, '' MacLife''. In 1997, the Ziff-Davis-owned '' MacUser'' magazine was consolidated into ''Macworld'' within the new Mac Publishing joint venture between IDG and Ziff-Davis. In 1999, the combined company also purchased the online publication MacCentral Online, because ''Macworld'' did not have a powerful online news component at the time. In late 2001 IDG bought out Ziff-Davis' share of Mac Publishing, making it a wholly-owned subsidiary ... [...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 is 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 sig ...

Zip (file Format)
ZIP is an archive file format that supports lossless compression, 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 Data compression, 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 (file format), 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 "Plus! 98" addon for Windows 98. Native support was added as of the year 2000 in Windows ME. Apple has included built-in ZIP support in macOS, Mac OS X 10.3 (via BOMArchiveHelper, now Archive Utility) and later.

Softonic
Softonic is a Spanish software download platform that distributes, categorizes, and evaluates programs for Windows, Android, and Mac. The platform was founded in Barcelona, Catalonia, Spain, in June 1997. History Softonic started in 1997 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 came from the "Files Library Intercom BBS" at Intercom Online, using a "5-step semi-automated process". The company also offered monthly CDs of its software library. In 1999, the service was described by El Tiempo as having a "generosity of games, antiviruses, education and the long, seductive et cetera." 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 downloads of DOS and Windows software, but it eventually had soft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EAR (file Format)
EAR (''Enterprise'' ''Archive'') 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. * META-INF/ ** application.xml: This is the main deployment descriptor for the EAR. It lists all the modules included in the EAR and specifies configuration settings. ** MANIFEST.MF: The manifest file that provides metadata about the archive. * JAR Files: ** These files contain Enterprise JavaBeans (EJB) modules or utility classes ...

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 fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compress (software)
compress is a Unix shell compression program based on the LZW compression algorithm. Compared to gzip's fastest setting, compress is slightly slower at compression, slightly faster at decompression, and has a significantly lower Data compression ratio, compression ratio. 1.8 MiB of memory is used to compress the Hutter Prize data, slightly more than gzip's slowest setting. The uncompress utility will restore files to their original state after they have been compressed using the ''compress'' utility. If no files are specified, the standard input will be uncompressed to the standard output. Description Files compressed by ''compress'' are typically given the filename extension, extension ".Z" (modeled after the earlier pack (compression), pack program which used the filename extension, extension ".z"). Most ''tar (file format), tar'' programs will pipe (Unix), pipe their data through ''compress'' when given the command line option "-Z". (The ''tar'' program in its own does n ...
