.lzh File Extension

Developer: N/A
File type: LZH Compressed File
You're here because you have a file that has a file extension ending in .lzh. Files with the file extension .lzh can only be launched by certain applications. It's possible that .lzh files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .lzh file?

An LZH file is a compressed archive of files implemented with compression specifications and standards used by the Lempel-Ziv and Haruyasu algorithm. Compressed files may contain multiple files or folders archived in one file integrated with specific compression and encoding specifications to reduce the combined size of all files and folders stored in the compressed file, and these LZH compressed files are integrated with encoding specifications used for the LZH file format. These LZH files are affixed with the .lzh extension and are used by many file compression and decompression applications locally developed by software design groups in Japan. The Lempel-Ziv and Haruyasu file compression algorithm was created by Lempel-Ziv and Haruyasu. Known as a file compression format derivative of the LZSS compression format, these LZH files are implemented with additional compression standards using dynamic Huffman coding. The Smith Micro StuffIt Deluxe 2010 file compression and decompression software can be installed in a computer running on Microsoft Windows-based systems to implement support for the compression and decompression of these LZH files. There are many file compression and decompression tools for Mac and Linux platforms that can be used to create and decompress these LZH files.

how to open a .lzh file?

Launch a .lzh file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .lzh file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .lzh files aren't yet associated with it. In this case, when you try to open a .lzh file, you can tell Windows which application is the correct one for that file. From then on, opening a  .lzh file will open the correct application.

a word of warning

Be careful not to rename the extension on .lzh files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .lzh. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
