Creates a new temporary directory.

The directory is recursively deleted when this object deallocates.
|
|
|
|
If you need a temporary directory on a specific volume use the `appropriateFor`
|
|
parameter.
|
|
|
|
- Important: If you are moving a file, ensure to use the `appropriateFor`
|
|
parameter, since it is volume aware and moving the file across volumes will take
|
|
exponentially longer!
|
|
- Important: The `appropriateFor` parameter does not work on Linux.
|
|
- Parameter appropriateFor: The temporary directory will be located on this
|
|
volume.
