public static File createTempFile(String prefix,

                           throws IOException

Creates a new and empty temporary file. By default, files are collected into one directory and are not deleted on exit from the VM, although they can be deleted by defining the system property poi.delete.tmp.files.on.exit (see DefaultTempFileCreationStrategy), which may cause OutOfMemoryError problem due to the frequent usage of File.deleteOnExit()

Don't forget to close all files or it might not be possible to delete them.

Parameters:

prefix - The prefix to be used to generate the name of the temporary file.

suffix - The suffix to be used to generate the name of the temporary file.

Returns:

The path to the newly created and empty temporary file.

Throws:
