If I have Google Drive integration, how is the 100MB limit on my account impacted by uploaded files?

Want to make sure my form users can upload files to my google drive, as opposed to jotform storage, to have greater flexibility in file size.

File storage limits refer only to files stored in your JotForm account.  If you remove the submissions that have files attached from your JotForm account, your total will decrease. 

The maximum file upload size can be increased.  Here is our quick guide detailing how to increase the limit as well as the maximum file sizes for different integrations:
