error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
volume path is a new path that specifies the volume on which the specified file or directory resides.
path out returns path unchanged.
size (bytes) indicates the amount of storage, in bytes, provided by the specified volume.
free (bytes) indicates the amount of storage, in bytes, available on the specified volume.
error out contains error information. This output provides standard error out functionality.
sector size (bytes) indicates the size, in bytes, of the smallest physical storage unit on disk. If you open a file without buffering, you must make the size of the data in that file a multiple of the given sector size.
