I checked this by attaching a debugger to an instance of explorer.exe and opening a folder that has a single file named "spam eggs.txt". With a breakpoint on NtQueryDirectoryFile, I changed the filename to "spam/eggs.txt" in the directory listing (an array of FILE_ID_BOTH_DIR_INFORMATION records). As expected, Explorer just displays the filename "spam/eggs.txt" if that's what the file system returns from the NtQueryDirectoryFile system call. However, even if a file system allowed such a name, it wouldn't be accessible normally. It requires a \\?\ path, which bypasses canonicalization. -- https://mail.python.org/mailman/listinfo/python-list
