Open/Extract LZH/LHA File with Freeware on Windows/Mac/Linux

LZH is a file compressed with the Lempel-Zip-Huffman algorithms. LHA is a freeware compression utility and associated file format. It was created in 1988 by Haruyasu Yoshizaki, and originally named LHarc. A complete rewrite of LHarc, tentatively named LHx, was eventually released as LH. It was then renamed to LHA to avoid conflicting with the then-new MS-DOS 5.0 LH ("load high") command. According to early documentation, LHA is pronounced like La.

The file format is not commonly used in Western countries, but is still quite popular in Japan. During the early versions of Doom and Quake, id software utilized LHA to compress their data files, and it was also the most popular compression format used on the Commodore Amiga. Microsoft has released a Windows XP add-on, Microsoft Compressed (LZH) Folder Add-on, designed for the Japanese version of the operating system. The Japanese version of Windows 7 ships with the LZH folder add-on built-in. Users of non-Japanese versions of Windows 7 Enterprise and Ultimate can also install the LZH folder add-on by installing the optional Japanese language pack from Windows Update.

Usually, LZH and LHA are the same. LZH is compressed with Lempel-Ziv-Huffman, but may be stored in a proprietary format. LHA follows the format specified by Haruyasu Yoshizaki and used in the LHA archiver.

LHarc compresses files using an algorithm from Yoshizaki's earlier LZHUF product, which was modified from LZARI developed by Haruhiko Okumura, but uses Huffman coding instead of arithmetic coding. LZARI uses Lempel-CZiv-CStorer-CSzymanski with arithmetic coding.

LArc uses the same file format as .LZH, but was written by Kazuhiko Miki, Haruhiko Okumura, Ken Masuyama, with extension name '.LZS'.
