The Quantum compression format is a little-known data compression method created by David Stafford of Cinematronics, LLC. It was licensed to Borland, Microsoft and Novell. ''Quantum'' is one of the possible compression methods in a Microsoft Windows CAB archive.〔http://www.cabextract.org.uk/ History of CAB files format〕 Quantum uses an extended LZ77 compression algorithm. Quantum archive files are named with the filename extension .Q by convention. ==Quantum archiver== PAQ.EXE is the Quantum compressor for MS-DOS and UNPAQ.EXE is the decompressor. These are 32-bit applications using a DOS extender from Borland. QWIN.EXE is the Quantum decompressor for 16-bit Windows. It is much faster than the MS-DOS decompressor and has more features such as selective decompression. A command-line tool COMPRESS.EXE supplied with Microsoft Windows or its resource kits up until Windows XP (up until version 5.00.2134.1 of COMPRESS.EXE) is able to compress files using the Quantum algorithm. All the Quantum compressors and decompressors require at least a 386 CPU in order to run. The last known version of Quantum released by Cinematronics is ''0.97''. 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「Quantum compression」の詳細全文を読む スポンサード リンク
