++ for readability, thanks!

If you inspect the zip file does it have a path inside? The problem might have been caused during the compression process.

The other thing to do is try it manually from the command line. Also, see if there are any flags you need to pass to your unzip program to make it behave more like what you want

Apologies, update added with correct formatting for code.
