For example, say you don't have read access to the parent folder - every path request further down should be "false" to you. Of course, one could make the case that there really should be three outputs: true, false, and "I'm not going to tell you one way or the other". Implementing the third option as an exception would make sense to me. Steve’s right – the mere existence of a file could be sensitive information.

It's probably safer to just tell you it doesn't exist. My suspicion is that for security reasons MS doesn’t want to tell you the file exists and that you don’t have permission.
