How can you discern a valid filename from a malicious one in a generic way?

More to the point, if a file has a name that would cause problems using that approach (e.g., because it has quotation marks in it), I still want to get the information about that file from the remote server.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
