Can I restrict users to upload certain file types only?
### Field Types

By default, submitters can upload any file extension to a File Upload question type.

You can limit this to specific file extensions by navigating to the question's configuration and toggling on "Restrict allowed file extensions".

## Gotchas

 - This filters the files in their operating system's file picker. They can still upload any file type if they remove the filter.
