How can I free upload space

Hi SBSinstalls,

Thank you for contacting Support.

You have to delete the submissions with file uploads to free up your file storage space. Unfortunately, there is no option to delete the files only. 

Guide to delete submissions: https://www.jotform.com/help/377-How-to-Delete-Form-Submission-Data.

Please make sure to keep a backup of the submissions and file uploads before deleting. Once deleted, they can no longer be recovered.
