Seriously, what the duck is up with OS X not being able to open password protected .zip files? Windows, being the laughed at victim of OS X, has been doing this for 12 years, out of the box!

As a selfnote I ask myself this:
Does the Unix command unzip -P password file.zip work on Macs? Actually, I ask you. I have no Apple stuff.

I just want to know what to tell my clients. If nothing else, this should be able to handle common .zip specification on OS X.
