If you have a full (and 100% resolved) path, you can prefix it with \\?\ (plus escaping) to access a file by that name, but I wouldn't recommend it as you'll probably break Explorer. In any case, this is an OS limitation and not a Python issue. ---------- resolution: -> not a bug _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24196> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
