Where can I see the uploaded photos in Google Drive?

Hi. our form is integrated with Google Drive for storage and collection of submitted forms. However, to my surprise, the 15GB allocation was already full and our form is still running. Then when i checked the folders of submitted forms, they are empty. but the user was able to submit the form. is there any way where can I locate the uploaded pictures/documents when the storage became full? it would be a big help if we will not message the users one by one to re-do again the form and submit. the form is used for registration so everyday we expect a lot of people visiting the page/form. 

You may check all the uploads on the submission page:

Are you unable to receive the uploads in Google Drive?

Looking forward to your response.

Thanks.
