Files that contain the .LZH file extension are compressed archive files. This particular file extension is given to archive files that have been compressed with the Lempel-Ziv and Haruyasu compression algorithm, named after the inventors who created the particular algorithm that is used with these files. The LZH file format is used when a user wants to take a batch of files or a single large file and compress the data into a single, compressed file archive.
These files in LZH files are compressed using dynamic Huffman coding. The LZH compression method is most popular in Japan, although it is sometimes used in other areas of the world as well.
