You can go to My Forms > select the form > Submissions:
Then you can select the submissions you wish to delete:
It is advisable that before deleting the submissions you download a submission list, making a backup, as we don't have a copy of them, and after deleting them they will be lost.
The submission list will only contain the data and links to the files, not the files itself. If you need to make a backup of all the files you can use the DownThemAll Mozilla Firefox Extension:
Let us know if we can assist you further.
