LZH file contains a file archive compressed using Lempel-Ziv compression algorithm and Huffman encoding, created by Haruyasu Yoshizaki in 1988. This compression method allow users to effectively conserve disk space taken by files.
ZIP extension is currently the most popular format used for archiving and compressing files and folders. Creating archives utilising the ZIP compression method is lossless, and it enables to reduce size of chosen files and folders. ZIP format enables compression utilising a compression method.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the LZH file after converting to ZIP may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from LZH to ZIP to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting LZH to ZIP does not meet your expectations, you can simply try to find on the Internet a different version of your file in LZH format, properly converted to a ZIP file by someone else. If this fails, use the information provided in the further part of the website.
Unfortunately, if after performing the two previously described steps (trying to find your LZH file converted by someone else, and the attempt to convert it to ZIP on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the LZH file in its original format (without conversion to ZIP file). Such a solution will be difficult to implement, but it certainly will give the best result.
