DeleteUploads finishers
The "DeleteUploads finisher" removes submitted files. Use this finisher, for example, after the email finisher if you do not want to keep the files within your TYPO3 installation.
Note
Finishers are only executed on successfully submitted forms. If a user uploads a file but does not finish the form successfully, the uploaded files will not be deleted.
Important
Finishers are executed in the order defined in your form definition.
