I'd go further and say that the OP is right in expecting Python to deal with the gory details. Would it break anything for Python to prepend \\?\ to all file names before giving them to certain APIs? Then the current behaviour of stripping off that prefix would be fine. Are there any times when you *don't* want Windows to use the extended-length path? ChrisA
