These are the third through seventh bytes of the file. In an LZH archive, the compression method is stored as a five-byte text string, e.g.
#BETTERZIP HUFFMAN COD INSTALL#
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. The Japanese version of Windows 7 ships with the LZH folder add-on built-in. Microsoft has released a Windows XP add-on, Microsoft Compressed (LZH) Folder Add-on, designed for the Japanese version of the operating system. This was due to Aminet, the world's largest archive of Amiga-related software and files, standardising on Stefan Boberg's implementation of LHA for the Amiga. LHA has been ported to many operating systems and is still the main archiving format used on the Amiga computer, although it competed with LZX in the mid 1990s. It was used by id Software to compress installation files for their earlier games, including Doom and Quake. According to early documentation, LHA is pronounced like La.Īlthough no longer much used in the West, LHA remains popular in Japan. It was then renamed to LHA to avoid conflicting with the then-new MS-DOS 5.0 LH ("load high") command. A complete rewrite of LHarc, tentatively named LHx, was eventually released as LH. It was created in 1988 by Haruyasu Yoshizaki ( 吉崎栄泰, Yoshizaki Haruyasu), and originally named LHarc. LHA or LZH is a freeware compression utility and associated file format.
