The original ZIP is 4.5MB. The contained ZIP is 2K when extracted with
WinZip 10.
The original file and the contained files are, I'm pretty sure, just a
Java JAR formatted file which I understood was built on the ZIP format.
I have DelZip179.DLL.
Here's the contents from one of the log files created:
