Convert 7Z to LZH

Understanding 7z and lzh file formats

7z is a popular compressed archive format developed by the 7-Zip project. It uses advanced compression algorithms, such as LZMA and LZMA2, to achieve high compression ratios. 7z files can contain multiple files and folders, making them ideal for efficient storage and transfer.

LZH is an older compressed archive format originating from Japan. It uses the Lempel-Ziv-Huffman (LZH) compression method and was widely used on Japanese computers and for distributing software in the 1990s. While less common today, LZH is still supported by some archiving tools for compatibility purposes.

How to convert 7z to lzh

Direct conversion from 7z to lzh is not typically supported by most archiving tools. The process usually involves extracting the contents of the 7z archive and then recompressing them into an lzh archive.

Recommended software for conversion

The best software for handling both 7z and lzh formats is PeaZip (Windows, Linux). PeaZip supports extracting from 7z and creating lzh archives. Alternatively, WinRAR and 7-Zip can extract 7z files, but only WinRAR supports creating lzh archives.

Step-by-step conversion using PeaZip

1. Open PeaZip and use File → Open to select your 7z archive.
2. Extract the contents to a folder using Extract.
3. Select the extracted files/folders in PeaZip.
4. Click Add and choose LZH as the archive format.
5. Set your desired compression options and click OK to create the lzh archive.

Alternative: Using command-line tools

On Linux, you can use p7zip to extract 7z files and lha to create lzh archives:

• Extract: 7z x archive.7z
• Create: lha a archive.lzh folder/

Summary

While there is no direct one-step converter from 7z to lzh, using tools like PeaZip or a combination of extraction and recompression allows you to convert your files efficiently. PeaZip is recommended for its ease of use and support for both formats.
