$TemporaryPrefix

$TemporaryPrefix
is a string that gives the path and beginning of the name for files and directories that are created by OpenWrite and CreateDirectory when no explicit file is specified.
  • Mathematica does not automatically delete files in directories specified by $TemporaryPrefix, although the operating system may do so.
