How to run/debug a script file its name has characters such as space, (, etc.

[jfong at ms4.hinet.net]

I saw a directory where all its filenames are something like this:
...
1a PSG (Entry and PopUp).py
1b PSG (Format).py
1c PSG (persistent form and bind key).py
...

Just wondering how these file can run and debugged under Windows?
