What is a LZH file?

LZH file extension represents a file format used for file archive compression. The Lempel-Ziv and Haruyasu algorithm is the base of this file format, hence the extension was derived as LZH (Lempel-Ziv and Haruyasu). This file format is almost similar with the other file compression formats like ZIP, RAR etc, in their purpose which is to twofold the files to reduce size and holding them together. LZH files are only popular in Japan and commonly used for compressing video game data. The Japanese versions of Windows have native support for LZH files but if you intend to use them in regular Windows PC, you will need tools like Winzip.
