What is an LZH file?

LZH files are a type of compressed file , similar to RAR files that you can unzip in Windows , but with a particularity. These have been compressed using specific software: the Lempel-Ziv and Haruyasu algorithm, named after the creators of the program.

This software is based on a previous one, called ‘LHARC Compressed Archive (.LHA)’, which is considered obsolete and has been replaced by LZH files. However, it implements a number of compression standards in addition to those used by this one.

This type of file is very popular in Japan , but not so popular in the rest of the world, where it is more common for you to be familiar with ZIP or RAR files. They have been widely used to compress and decompress files developed locally by design groups of some video games, such as Doom.

Like other compressed files, LZH files serve a dual purpose or purpose. On the one hand, they allow you to reduce the size of the files it contains, so that they don’t take up so much space on your PC. And on the other hand, it allows you to have several files together in one place.

The software that allows compressing and decompressing files with this format can be used in operating systems derived from Windows, Ubuntu and Mac without any problem. In addition, there are multiple tools that you can use to open an LZH file, as we will show you in the next section.

How can I open a compressed LZH file on my PC?

In Japan, computers with Windows operating system come by default the necessary software to open compressed LZH files without the need to install any additional programs. But if you don’t have a Japanese version of Windows, there are also options for you to open these files.

LZH compressed files can be opened using other software that you already know , and possibly even have on your PC. Then we will leave you a list of them so that you can check if you have them already installed, or if you need to download one.

  • Corel WinZip 16 Pro, which allows you to choose the compression level and method you want to use.
  • WinRAR, which will allow you, of course, to create RAR files.
  • ConeXware PowerArchiver, which enables advanced compression format.
  • 7-Zip, which will also allow you to compress files in Windows
  • PeaZip, a Windows compatible freeware compression tool.

As we have already mentioned, it is most likely that you have one of these programs already installed on your PC, as they allow you to open and create other compressed file formats. However, in case you don’t have them and don’t want to get them, there are other options you can try to open LZH archives.

Even if you don’t have the Japanese version of Windows, you can open a compressed LZH file on your PC easily, without any of the programs designed for this task that we just mentioned. You would only have to install the ‘Microsoft Compressed (LZH) Folder Add-on’ on your computer.

You can get this plugin very easily through Windows Update by downloading the Japanese language pack . If this option seems more feasible, on the official Microsoft Support page you can see how to obtain language packs for Windows in different versions, from Windows 7 onwards.

Can I convert an LZH file to another format?

Although this is unlikely to give you any benefit, you can convert an LZH file to another type of compressed file , such as ZIP, CAB, and TAR, among others. To do this, you can use file converters such as FileZigZag and Zamzar, which allow you to do other conversions, such as converting Project to Excel , for example.

However, it is probably more useful for you to extract the files contained in the LZH file, whatever their format, and then convert them to the format you want . We hope this information has helped you to learn how to open a compressed LZH file on your PC quickly and easily.
