About .LZH File Format
To do word count in LZH archives, let’s get to know a little more about this format.
LZH (LHA) is a freeware compression utility and associated file format. Created as LHarc in 1988 by Haruyasu Yoshizaki (吉崎栄泰, Yoshizaki Haruyasu).
No longer much used in the West, LZH remains popular in Japan. It was used by id Software to compress installation files for their earlier games, including Doom and Quake. Japanese versions of the Windows operating system still include LZH support
7-zip, WinZip and WinRar can open LZH files in read-only mode.
