Gravity Perks File Renamer renames files uploaded with Gravity Forms. You specify a naming template, and files are renamed when the form is submitted.

Templates support static values and merge tags, so a filename can include the user’s first and last name. You can add a prefix and suffix, add numeric increments per field, and control how duplicate filenames are deduplicated. Custom upload folders can group all files from a submission into a folder named with the entry ID.

It works with File Upload, Multi-file Upload and Post Image fields. It also works with File Upload Pro fields, adds Unique IDs to filenames and stores renamed files in the Media Library. All languages and character sets are supported.
