The path to which temporary files are written at runtime.
If you are planning on working with binary files or large files, it is recommended that you set a valid path for this property. When set to a valid path this property tells the task to use temp files when performing operations. If this is not set, all operations are done in memory and require that all input and output is in ASCII.
This property accepts the "%TEMP%" macro, which will be replaced with the default system temporary directory at runtime.
