Convert CAB to LZH

Understanding CAB and LZH file formats

CAB (Cabinet) files are compressed archive files developed by Microsoft, commonly used for software distribution and Windows installation packages. They support a variety of compression algorithms and can contain multiple files and folders in a single, compressed package.

LZH (Lempel-Ziv-Huffman) files are compressed archives that originated in Japan and are popular for distributing software, especially on older platforms. LZH uses a combination of Lempel-Ziv and Huffman coding for efficient compression.

Why convert CAB to LZH?

Converting a CAB file to LZH format may be necessary for compatibility with legacy systems or software that only supports LZH archives. It can also be useful for users who prefer the LZH format for its specific compression characteristics or regional popularity.

There is no direct one-step converter for CAB to LZH, but you can achieve the conversion in two steps:

1. Extract the contents of the CAB file using an archive manager.
2. Compress the extracted files into a new LZH archive.
