Info-ZIP is a set of open-source software to handle ZIP archives. It has been in circulation since 1989. It consists of 4 separately-installable packages: the Zip and UnZip command-line utilities; and WiZ and MacZip, which are graphical user interfaces for archiving programs in Microsoft Windows and classic Mac OS, respectively. Info-ZIP's Zip and UnZip have been ported to dozens of computing platforms. The UnZip web page describes UnZip as "The Third Most Portable Program in the World", surpassed by Hello World, C-Kermit, and possibly the Linux kernel. The "zip" and "unzip" programs included with most Linux and Unix distributions are Info-ZIP's Zip and UnZip. In addition to the Info-ZIP releases themselves, parts of Info-ZIP, including zlib, have been used in numerous other file archivers and other programs. Many Info-ZIP programmers have also been involved in other projects closely related to the DEFLATE compression algorithm, such as the PNG image format and the zlib software library. ==Features== The UnZip package also includes three additional utilities: * fUnZip extracts a file in a ZIP or gzip file directly to output from archives or other piped input. * UnZipSFX is software to make a ZIP file into an executable self-extracting archive. * ZipInfo outputs, in a variety of formats, information about ZIP files and their contents. The Zip package includes three additional utilities: * ZipCloak adds or removes password encryption from file in a ZIP archive. * ZipNote allows the modification of comment fields in ZIP archives. * ZipSplit splits a ZIP archive into sections for separate disks or downloads. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Info-ZIP」の詳細全文を読む スポンサード リンク
