In which scenario? \\?\C:\ is just the same as \??\C:\ in NT speak, and that's a perfectly valid directory path. > 2) > unmounted network drives (\\server\path) Yeah, those have a different prefix: \\?\UNC\server\share > I'm not sure how a --unc should handle those cases. > For all things I have in mind, not appending \\?\ is preferred, but someone > might expect a hard error. > > Either way, it is another reason why it makes sense for cygpath to handle > those cases, currently I have to parse it's output before prepending '\\?\'.

Nobody should actually need this nowadays, and sometimes short paths don't even exist. It's a functionality inside the FS driver, afaik, and it can be switched off in the system. In your example, standard filenames work: $ cd /cygdrive/c $ mkdir test. $ cd test. $ cygpath -ws . cygpath: cannot create short name of C:\test. $ cygpath -wa . C:\test.
