This PEP proposes to fix these problems by re-publicising the feature, defining the .pyz and .pyzw extensions as “Python ZIP Applications” and “Windowed Python ZIP Applications”, and providing some simple tooling to manage the format. There is a bug in Windows Powershell, which is apparently due to a bug in the underlying FindExecutable API, that can fail to recognise extensions which are longer than 3 characters properly. Rather than risk obscure bugs, I would suggest restricting the extensions to 3 characters. For the “Windowed Python ZIP Applications” case, could we use .pzw as the extension instead of .pyzw? Please don't shoot the messenger here - I'm not going to try to defend such a stupid Windows bug, but better to be safe in my view. Flames about Windows to /dev/null...

I'm OK with the shortened extension.

Cheers, Nick.

Paul.
