Deleting uploads

If I understand you correctly, you would like to delete the file uploads to clear up your upload space. You need to delete the actual submission that has the attachments in order to delete the uploads. Please follow the steps below:

In My Forms page, select the form and then click the "Submissions" button.

After that, you'll see a "Delete" button at the top right.

At the bottom, in the Grid Report, you can also see a "X" button to delete a submission. There is also an option to "Delete All Submissions".

Hope that helps. Thank you.
