Welcome to the BlackBerry Support Community Forums.
Thanks for the question.
Once a file is deleted from the BlackBerry smartphone it can not be retrieved. Depending on the type of the file it could be included in your backup file saved on your PC or Mac. You can attempt to do a full restore in BlackBerry Desktop Software by going to Device>Restore.
Let me know if you have any more questions.
