Lhasa (pronounced as /ja/) is a Japanese computer program used for unpacking or decompressing files in various compressed formats, including LHA (LZH) and ZIP. Lhasa is an open-source utility specifically designed for handling LHA compression, which was a common format for archiving files in early computer systems.
The development of Lhasa likely began in the early days of computing when the LHA compression format gained popularity. The LHA format, also known as LZH, was widely used in the 1980s and 1990s for archiving files on systems like the Amiga and early versions of Microsoft Windows.
