Inputs/Outputs

  • cpath.png path —

    path specifies the path to the file or folder you want LabVIEW to look for.

    If you use this VI to check the validity of a network path, make sure that you connect to the network first.

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • ipath.png dup path —

    dup path returns path unchanged.

  • ibool.png file or folder exists? —

    file or folder exists? is TRUE if the file or folder you specify in path exists on disk and FALSE if the file or folder you specify in path does not exist on disk. If you wire an empty path to path, file or folder exists? returns TRUE because the empty path refers to the list of drives mapped to the computer. (macOS) The empty path refers to the mounted volumes. (Linux) The empty path refers to the root directory.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
