LHA-LZH files
There is an MS-DOS version of the LHA program that can decompress both
.LHA and .LZH files. (You'll have to rename the .LHA files to .LZH).
Look for the program lha213.exe in one of the IBM forums. Note that you
may run into some problems due to the MS-DOS 8.3 file name limits, but the
files should decompress properly.
Hope this helps….
