FileNameJoin

FileNameJoin[{"name1","name2",…}]

joins the namei together into a file name suitable for your current operating system.

FileNameJoin[{CloudObject[…],"name2",…}]

joins the namei to the path in the specified cloud object.

Details and Options

  • The "namei" can be either individual names or file paths containing pathname separators.
  • FileNameJoin[{"","name1",…}] gives an absolute file path beginning with a pathname separator.
  • FileNameJoin[…,OperatingSystem->"os"] yields a file name in the format for the specified operating system. Possible choices are "Windows", "MacOSX", and "Unix".
  • FileNameJoin just assembles a file name; it does not actually search for the file specified.
  • FileNameJoin["name"] canonicalizes the file name "name", making pathname separators appropriate for your operating system. FileNameJoin also works with file-based URLs.
